I too consider myself a lost cause.
I never got to have a normal childhood because my mom chose to stay with my violent alcoholic father who abused me and my brother 24/7. He never held a job, or supported us and slept in bed all day drinking booze. I never learned any viable lessons or life skills because he didn't care enough to teach me anything. I was held back twice in middle school due to my terrible upbringing and had failing grades.
Most of my friends abandoned me in middle school, and I was stalked/harassed during my teen years by a terrible group of friends over a fight and couldn't fully escape them until I made new accounts to get away.
I was hospitalized for a suicide attempt back in April and met my ex there. We fell in love and he abused me during our time together and discarded me in November. I want to believe karma will hit him one day but I doubt it will.
My last psychologist was a piece of shit who kept interrupting my sessions that my family paid for to do something else in the background and downplayed the trauma I went through in my childhood, then told me the same half-assed advice everyone has already told me before.
My family is sick of my shit, I've been scolded by my brother over everything just because I was angry my keyboard stopped working properly, and my mom blamed my breakup on the perfume I was wearing.
I am done with life, all I've ever known is abuse, abuse, and abuse. From everyone around me. Even if some troll on a video game told me my life was worthless over some petty argument, I'd believe them.
