You're not the only one to feel like this, anon. Unfortunately, I can't offer much in the way of useful advice. Most likely no one's coming to save you and you'll have to pull yourself out of the hole. It shouldn't be like that, people aren't wired to operate alone like that, but you have to play the hand you're dealt.
I can say that the hopeless feeling is a self-perpetuating feedback loop and the longer you sit in your current state the harder it will be to get out of it. You're gonna have to take your life in your hands and fight like hell to make it something you can be satisfied with.
If you have any special interests or hobbies, try to get involved in spaces for those and make some friends. Don't go trauma-dumping on people but you can build a little bit of a support network that way.
If you really have no attachments in your current life and absolutely nothing to lose, consider just jumping into some major change to your circumstances as "shock therapy." Get an interesting job 1000 miles away, go join the French Foreign Legion, do something crazy and throw yourself to the wolves. It will almost certainly go poorly, but if you're already at rock bottom it may be worth a try.
I know I'm just some anonymous faggot on the internet, but I'm cheering for you. Good luck out there anon.
