Feeling completely lost

I don’t know what to do with my life anymore. I used to have some idea but it all came crashing down on me in the last few years. I can barely manage to leave my bed and get something to eat. I’ve been doing virtually nothing every day for months. I‘m lonely as fuck it feels like a crushing pain in my chest. I miss having a community even if my friends in the past were ass. I miss having multiple people to talk to. I have one online friend but he’s been pretty distant lately and it’s really eating at me. I feel like nobody values me like I value them. I feel like I’m destined to die alone without accomplishing anything of value
