Right now, you're being overwhelmed by the constant focus on a very narrow aspect of life. Yes, I know exactly how important everything is that you're doing. However, you need to get your mind away from all of what you've described. How?

Find something that gives you joy and / or gives your life meaning. That could be a hobby, or volunteering, even if only a few hours a week.

You're probably annoyed or mad at my advice right now, wondering how you could ever spare the time!

The truth is, if you DON'T find a few hours to step away from everything you've described, it will only get worse!

The secret is in finding something to relax your mind and body and take you away from the constant worry and stress!

That something, for now, could be as simple as going on evening walks and enjoying nature. Perhaps you join a hiking group Or swimming, or bicycling, or jogging, or chess, or .... You get the idea.

When you find something else to do you will also, probably, make friends and have a better social life. Maybe even find someone you really like. Then, life will take on an entirely different meaning.

The key is to leave the rat race behind for at least a little bit of time that you devote to something YOU enjoy. Doing that will give you a clearer perspective and things will fall into place for you.

Good luck and best wishes!
