I'm repeatedly making "busy" friends or ones who flake, and i'm not sure what to do

None of your friends care about you because you don't care about yourself. If you think your friends are "busy a lot" and you aren't also "busy a lot," you probably don't have much of a life outside of your friends. Be someone other people actually want to be around and maybe all your "friends" won't flake on you. Take some fucking responsibility and initiative for yourself.

"Oh boo hoo, the world doesn't like me, waaaaaaahhhhh." Christ, all this whiney shit on this subreddit. Here's the big secret the entire world doesn't want you to know: to keep your friends, you need to be someone people don't want to flake on. You're probably boring as fuck with no interests or conversational skills.

Dude, I'm 21. I don't have time to fucking deal with someone like you and all the associated bullshit. I have my own fucking life and your issues don't need to diminish my quality of life. I like to spend my time with other people I think are awesome. If you bore the ever loving hell out of me and I feel like I'm only friends with you out of sheer pity, then yeah, no shit, I'm not going to invite you to things or want to hang out with you in situations in which I don't absolutely need to. You're probably a bummer and/or reallllllllly boring/two-dimensional.
