Can’t do this anymore...

I feel like everyone hates me. My parents get mad at me all the time, my “best friends” leave me out of things. I’m just so done and over this shit. I suck at school and ppl think I’m dumb including my friends. I’m never gonna make it anywhere. I have dreams of having a really good job in the medical industry but Ik that’ll never happen. My feelings get hurt all the time and I’ve had the worst few days. Today I had a knife to my stomach and didn’t have the guts to go through with it. I’m 16 and my life is already over. (Sorry didn’t rlly know where to post this) thanks for reading :(
