Psychosis/Depersonalization

Does anyone here struggle with these? I was diagnosed as a teen but it just seems to be getting worse. My pregnancy was the worst mental experience ever. My daughter is 10 months old and it’s only a little bit better.

I don’t know how to cope with it. I feel so strange almost all the time. I’m constantly worried that I’m dying, even though I have no real reason to feel that way. I don’t like to be around people, but I hate being alone. I really don’t have anyone for support.
