How sick are you? If all you have is omicron you don't need to worry much. You will be over it in a few days.

If you test positive, your self-isolation period includes the day your symptoms started (or the day you had the test, if you do not have symptoms) and the next 7 full days. If you get symptoms while you're self-isolating, the 7 days restarts from the day after your symptoms started.



You can leave self-isolation after 7 full days (on day 8 of your self-isolation period). You should take a lateral flow test (LFT) on day 6 of your self-isolation period and another lateral flow test 24 hours later. This is to check if you remain infectious and could pass COVID-19 on to others.

You should not take a LFT before the sixth day of your self-isolation period because the risks of remaining infectious and the chances of passing it on to others before this period is significantly higher.

If you are a close contact of someone who has tested positive for COVID-19, you should follow this guidance. If you are not fully vaccinated, you are legally required to self-isolate as a close contact for 10 days.

CDC says:

To calculate your 10 full day isolation period, day 0 is your first day of symptoms. Day 1 is the first full day after your symptoms developed.

And I hope you get well soon.
