First thing to do is have compassion for yourself. Recognize that you have to put up with difficult things in your life and that it’s hard to do so. I found that when I’m by myself, which is most of the time, I’ve become much happier and more content when I make art and be creative. Having a creative output can help process emotions. It doesn’t even have to be good, just something you made in whatever art form. And also, being what society would call a “loser” is ok. Don’t force yourself to go out unless you want to. Yes you do need to push your limits and get out of your comfort zone at times but don’t pressure yourself. Basically, for me at least, you have to first put yourself together and find that self love again before anything else. I wish you the best of luck
