Does anyone else feel scared of themselves? Like they can’t trust themselves and even waking up in their own body is so isolating cause they just want to escape their brain?

If I tell you yes or no, I would be giving you reassurance of your fears. The question you're asking is a compulsion. Don't let OCD trick you! Maybe write down some scenarios where you do the things you are scared of. Lean into the anxiety that it causes, but sit with it when it happens instead of finding a compulsion to get out of it.
