How to relax during the pandemic?

Turn off the news. Covid is a hoax.

Don't listen or watch the news too much, that's most likely driving your anxiety over this. Also stay away from things that are known to have fake news. Try to keep your self distracted, and try to be more positive. Pick up a hobby, they can help reduce your stress. Also bloody stools, not a symptom of covid 29.
I have a stress fracture and arthritis in the same foot. I have to do what I can to make my self healthier and stay safe. I've  been at home since the last week of March. I've only gone out for medical appointments and to curbside pick up groceries. 
As long as you're doing what you can to prevent your self from getting covid, that should give you some peace of mind. 
Every one is tired of it you're not the only one.

Every symptom does mean you have covid-19.
But the CDC is now reporting that between 40-45% of people are asymptomatic.
Since almost a majority don't even know they have it, it's not really so freaky.

And although the news likes to show you young and vibrant people who have covid or died of covid, that's not how most people are who have serious complications.
- Over 1/3rd of all deaths are in nursing homes where many people don't even want treatment because of existing conditions.
- The current hospitalization rate is down to less than 5% from 20% last March.

I'm not aware of mass hysteria.  I'm aware of some stupid people but that's not the masses.  Most people have figured out how to live their lives with limited risk in the last year and really aren't afraid of it (they don't want it but they aren't afraid of it).

Well first of all, you can get other things besides COVID and it might make you more sick than the virus.  As far as you actually getting it, the chances are slim to none,  especially if you've tested negative. If you get the vaccine, even better.  Blood in the stools is common and is not a symptom of covid.  If you were to get covid, you have to keep in mind that many people get it and don't have any issues or major symptoms where they end up in the hospital.  A majority of those who got very sick or died had pre-existing conditions.  We are hopefully near the end of this, so try to not look at every single news article.  There are so many, and it's just overwhelming.  Try not to be around large crowds, and you can go back to living your life as close to normal as it was before.  Do meditation with some aromatherapy, soft soothing sounds (like a white noise machine) to get you to sleep, and get some fresh air and exercise daily.  Keep yourself busy with hobbies and interests, or take a class online which will keep you focused on something else.  Illnesses come and go, so keep that in mind and try to be positive.  

u should get vaccinated
