I feel the same way. What do we do to make it stop?
Unfortunately, I haven't found a magic formula. I've found ways to simply bear it, like when you take painkillers for back pain so that you are able to keep working.
Later I will go and have an ice-cream at the park, buy a decaffeinated coffee and sit on a bench watching the birds. I know this will calm me and allow me to reflect. Then, I know when I get back home, I will be able to do some reading and learn something new (amateur coder here, so learning some .NET MAUI basics). This will help a little, because then I know my day wouldn't have been totally wasted. I listen to some music that numbs the pain for a while. I try to pray at least once per day and I am not mad at our Creator, because I know my troubles come from how society works and how people exclude you and mistreat you when they, for some arbitrary reason, don't like you. I know I made mistakes in the past. And I know nobody promised me it would be easy.
I applied for some jobs, so I got to stick around and see the outcome, although I have no enthusiasm. But that new job, whenever it comes, will possibly distract me from negative thoughts for a good part of the day, I hope.
So you see, it's as if I am giving myself carrots that help me carry on, hoping for those better
dayz.
I wish I could just know the answer. It isn't 42 for sure. It is much more complicated than that.
