also bud you're 18? i was posting about edgy bullshit when i was 15 and just made an account. (yes i also just turned 18 yesterday. i'm not kidding)
skimming through your posts you clearly have self awareness but you must push people away from you (just read your new post, its safe to assume)
having people care about you makes existence a lot more worth it. you don't see it that way but i know i'm talking to a brick wall. when shit hits the fan and nobody is there to actually listen to you, it takes a real toll on the mind. you may think you're so tough that you don't need anyone to care about you, but you gotta take care of things somehow. bottling things up is how you explode, usually in yelling or violence. I know from personal experience.
i'm not sure what has twisted your mind into being so edgy and shit, but you gotta try to change. working a job requires people at least tolerating you and your mindset screams 'homeless at 20'. i'm not gonna post about this again until you begin to finally sort your life out.
I'm 18 and I would dare say I have things sorted out with many people having my back if things go wrong. I know how to make money and who to go to if things get tough. I have a good work ethic and how to keep a job. Managing finances is also a nice skill, and I'm also willing to take advice because I know I will never know everything. I only make posts like this if OP is like you and might listen, even if it takes a while.
TDLR: drop the bullshit, be likeable, sort your shit out, and realize how valuable having people care out you. or not, life is a harsh teacher.
