I'm gonna become more of a loser ambitionless doormat by my own self volition

I don't want to beleive in myself ever again or have even a shred of any self confidence again because every time I do I get burned back sooooo hard it's just not worth it anymore ok.....

When I stand up to people who treat me bad they treat me worse and when I try to make friends I embarrass myself and when I try to flirt with girls I fail miserably whatever whatever ugh
