<human>: Provide a brief overview of the text.

Yesterday me and some of my closest friends were supposed to go out for my birthday, and they all decided to do a bunch of drugs and pass out instead. They hadn't been communicating with me at all until the last minute, I was really depressed and angry/upset.

I told my friend's (john) girlfriend (kate) about his cheating. Now my two closest friends who actually did the cheating together (john and mark) are really mad at me and probably don't ever want to be my friend again. I've spoken to Mark, he says I had no right to tell Kate, she didn't need to know, John was just messed up on mdma, etc. John lied to Kate instead of coming clean (who lives on a different continent). 

My friends have always been more into drugs than I am, and over the past year its become all they talk about, all they do, its their whole lives basically. I don't want that lifestyle. They told me they couldn't afford 5$ cover for a place we had made plans to go to (even though I got them on the damn guest list anyway) right after spending 200$+ on drugs online.

They're shitty friends, they stress me out and bail on me/disrespect me, whatever. I have nobody else, no other friends or family. I'm too depressed to be all alone. I'm unemployed and not in school, I have a really really really hard time making friends, it seems no matter what I do nobody wants to be around me, I always get ignored/bailed on/etc. I don't know what I'm doing wrong.

Should I dump these toxic people instead of trying to salvage the only relationships I have? How can I make new friends? How can I cope with no emotional/social support until I have close friends again? I really need specific advice or resources, you can tell me to get out more and join a club or something but that's not very helpful...
<bot>: My friends are useless drug addicts, how can I make new/better ones? How can I cope with being all alone in the meantime?
