Don’t know what to do

I know things aren’t that bad but I’m really struggling. This guy i like and have a situationship and it’s tricky because i don’t know what to do with it. I’m not sure what I want but I know I like him a lot and I know he feels the same exact way about me. We haven’t had sex but I let him finger me and of course right after that encounter he’s being fucking weird and distant. I’m not chasing him, I just don’t have it in me emotionally too. We’ve been doing this for too long now and if it’s over then it just is. I can’t communicate for the life of me, and i know it’s not healthy and I’m currently in therapy trying to work on myself because I’m hurting. My best friend just blocked me on everything and she’s been my friend since pre-k and I’m 21 now. That situation I don’t think I’ll be able to fix easily smh. I don’t have many friends and I’m not taking care of myself. I haven’t been eating, showering, taking my meds, and found that Tylenol PM is my new best friend bc it’s the only way I can sleep. That’s also not healthy. I feel like im sinking
