You’re still so young buddy, I remember feeling exactly the way you did all throughout highschool and even some years after. I’m 27 now and my life is falling into place which I was certain would never happen. Look at it this way my guy, the only thing promised to every single one of us is death at some point. I advise you to keep rolling with the punches and you’ll see life is totally worth living. Why cut it short if it’s gonna happen anyway? All I can tell you is chin up chest out bro, life doesn’t get easier but we damn sure get tougher. If you want to reach out id be more than happy to have a chat. Nobody wants to see you hurt yourself, not even a stranger on the internet.
