I need help and friendly support

I’m supposed to be quitting nicotine weed alcohol at the same time but I’m vaping still and ripping burnt weed carts and I can’t stop thinking about going to buy alcohol what do I do? I’m in a small town with nothing to do like when I say nothing I mean it the movie theater just got torn down which was the last good thing now it’s a no frills. I got no friends so I don’t ever have plans or go anywhere I just sit at home thinking what video game to play but I’m at the point where I don’t even wanna play games idk what to do I’m lost and I’m sorry if I’m being a nuisance or if this is the wrong community for this. I just don’t know how to quit and I’m scared of being alone so treatment scares me and I’ve been hospitalized 3 times like can someone please help even if it’s just a small sentence please❤️
