Hey, im 22 y male 
I feel so bad every time I wake up like I'm choking myself from the inside.

Why I'm feeling that way?
It's because I see myself not doing enough in everything   and i feel that I am not important in anyone's life like why I'm still alive. And i feel that no matter what i do it's just not enough and its killing me slowly.
None of my friends know about this because I can hide it.
And i feel like doing anything isn't worth it at all and i should stop doing whatever I'm doing 
I dont know what to do i just need it to stop.
PLEASE HELP ME!!
