Do you normally have friends IRL that you hang with? I think that we are social creatures, and for most of us, we need to be with others, maybe not always, but certainly to some degree. I was an only child with no brothers or sisters, so I always had a best friend, someone I could spend time with and be close to. Once I became married, my wife became my best friend, and of course, we have always been close to our children.
I hope you have some friends that you can talk with, go out doing things. To be alone can cause terrible depression. I know that some people prefer to be alone, but that's never been me. I hope things get better.
