Long Covid Low Mood and Anxiety: What to Log

Updated 29 Oct 2026

Months of fatigue, breathlessness, and brain fog wear on mood too. On a flat day it is hard to tell whether low mood is part of a crash, a reaction to a setback, or something that needs its own help.

This guide covers what to log about low mood and anxiety with Long Covid: urgent help first, a daily mood score beside physical symptoms, the two-week mark, triggers, and what helps. Your GP or care team makes the assessment.

Get help first if you are in crisis

The NHS says support is available if you or someone you know is having a mental health crisis or emergency, no matter what you are going through (NHS low mood guidance). It lists having suicidal thoughts or thoughts about harming yourself among symptoms of depression (NHS low mood guidance). If you feel this way, contact urgent mental health help or emergency services before you write anything down.

The NHS also advises getting the details of who to contact if you are worried about your symptoms or need more help and support (NHS long COVID guidance). Save those details somewhere you can find them on a bad day.

Once you are safe, the log can wait until you have the energy for it. A record helps with the next appointment; it is never a substitute for getting help now. Telling one trusted person how you feel is a good first step too.

In Long Covid Journey, My Care Team keeps the contacts you were given.

How to log mood beside physical symptoms

The NHS lists the most common long COVID symptoms as feeling extremely tired (fatigue), shortness of breath, joint pain and aching muscles, and problems with your memory and concentration, also called brain fog (NHS long COVID guidance). It lists difficulty sleeping (insomnia) and anxiety and depression among other symptoms (NHS long COVID guidance).

It says a general low mood can make you feel sad, anxious or panicky, angry or frustrated, and low on confidence and self-esteem, and it can also make you feel tired or cause problems sleeping (NHS low mood guidance). Fatigue, poor sleep, and low mood overlap, so log them side by side.

Each evening, score mood and anxiety on a simple 0 to 10 scale, next to fatigue, sleep, and brain fog. Add one line on what the day held. After a few weeks, the log shows whether low days follow crash days, poor nights, or neither.

For more than a fatigue number, see what to track besides a fatigue number.

In Long Covid Journey, the Daily check-in holds mood beside other symptoms.

How to log how long it lasts

The NHS says a low mood often gets better after a few days or weeks (NHS low mood guidance). It says a low mood that lasts 2 weeks or more could be a sign of depression, and other symptoms may include not getting any enjoyment out of life, feeling hopeless, and not being able to concentrate on everyday things (NHS low mood guidance).

It advises seeing a GP if you have had a low mood for more than 2 weeks, you are struggling to cope with a low mood, or the things you are trying yourself are not helping (NHS low mood guidance).

Mark the first day mood dropped, then count. If it reaches two weeks, that date is the reason to book. Also note enjoyment and hope, because those two lines describe depression symptoms the NHS lists, separate from the brain fog of Long Covid.

In Long Covid Journey, the Flare Tracker marks the start of a low stretch.

What to log about triggers

The NHS says you may find your long COVID symptoms get worse if you are stressed or have been more active, that some symptoms may get better or come and go, and that you can get new symptoms you have not had before (NHS long COVID guidance). It advises keeping a diary to track what makes your symptoms better or worse (triggers) (NHS long COVID guidance).

For low mood, it lists causes including work pressure, family and relationship difficulties, financial problems, and health, such as illness or injury (NHS low mood guidance). It notes that sometimes it is possible to feel low without there being an obvious reason (NHS low mood guidance).

Beside each low day, note activity the day before, stress, sleep, and any setback, such as a canceled plan or a hard talk at work. Leave the line blank when there is no reason. A blank is useful information too.

In Long Covid Journey, the Daily Journal keeps triggers in your own words.

What to log about what helps

For a low mood, the NHS suggests trying talking about your feelings to a friend, family member, healthcare professional, or counselor, considering peer support, and trying mindfulness techniques (NHS low mood guidance). It advises not trying to do everything at once and setting small targets you can easily achieve (NHS low mood guidance). It also advises trying not to use alcohol, cigarettes, gambling, or drugs to relieve a low mood (NHS low mood guidance).

The NHS says you may find it helpful to get support from other people with long COVID, either at a local support group or online (NHS long COVID guidance). It lists using tools like apps to track your symptoms among long COVID treatments (NHS long COVID guidance).

Log one thing you tried each day, such as a call with a friend, a short mindful pause, or a small target met, and whether mood shifted after it. Over time, the list shows which supports fit your energy on hard weeks.

In Long Covid Journey, Weekly Goals keeps small targets for the week.

What to bring to your GP or care team

The NHS says that with long COVID you will be supported by a team of different healthcare professionals, who will look after your physical and mental health (NHS long COVID guidance). Treatment may include cognitive behavioural therapy (CBT) to help with anxiety, depression, and fatigue, and activities to improve memory, concentration, thinking, and mood (NHS long COVID guidance).

For low mood, the NHS says you can sometimes refer yourself directly to an NHS talking therapies service, depending on your age and area (NHS low mood guidance).

Bring the date mood dropped, the weekly mood scores beside fatigue and sleep, the triggers you noticed, and what helped. Ask whether the plan should include support for mood, and write the answer in the log. Family who do not see the hard days may need a simple explanation too.

In Long Covid Journey, the Doctor Report turns the weeks into a summary.

How Long Covid Journey can help

A notebook can hold one bad day. The harder part is keeping mood, sleep, fatigue, triggers, and what helps in one dated record.

Long Covid Journey is a personal Long Covid tracker from Health Journey Labs on the App Store and Google Play. It records symptoms, medicines, test dates, and visits in one dated history. Below is what you can use and how each part helps:

• Daily check-in — A short guided pass across symptoms, mood, nutrition, sleep, exercise, meds, and external factors, including fatigue, breathlessness, and brain fog, so links you would not remember on your own show up side by side.
• Daily Journal — Freer notes, including voice on foggy or low-energy days, that add detail a score alone cannot show.
• Flare Tracker — Mark a crash day, so you can tell a one-off bad day from a repeating pattern after effort.
• My Meds — Medicine names and timing, so you can line up a start date or dose change with symptom days.
• My Labs — Result dates for blood tests, heart and lung checks, and other tests, so each result sits next to how you felt that month.
• Weekly Goals — Set one small aim, such as a regular bedtime or a paced walk, and see whether it held and whether symptoms changed.
• Learn — Short education topics on long COVID themes such as pacing, sleep, breathing, and visit preparation.
• AI companions — Clara and specialist companions already see your logged history, which helps with pacing ideas or visit wording.
• My Care Team — A profile for each clinician, plus upcoming appointments and notes for each visit, used before, during, and after appointments.
• Doctor Report — Two views: the Appointment Planning Report helps you prepare what to ask, and Generate Report, opened from a saved doctor, builds a dated summary of your recent progress for that doctor.
• My Assessments — Structured check-ins that add context about you across weeks.
• Food Tracker — Meal and drink lines, so you can line up appetite, meals, and gut symptoms with energy.
• Period Tracker — Cycle dates, so you can see whether fatigue or crash days cluster at a certain point in the cycle.
• Weight Tracker — Weekly weights, useful when appetite is low or weight is changing.

Everything you log builds one history. Guided forms include the key questions, and you can add custom symptoms when you need your own labels. Long Covid Journey is free to download.
