Im upset and im here to vent

Ik its easy to just blame it on being a loser incel bitch, but god, my family can really fucking ruin my year. My bro is borderline retarded and has no ability to interact with people appropriately, he just kinda does whatever he wants without taking into consideration on how it may affect me, and when I call him out on it or get pissed, I suddenly become the bad guy. My mother, as much as I love her, God bless her, she can be super fucking unreasonable, it's fucking awful. she just doesn't get stuff. It's like she's oblivious to stuff at times, its fucking horrible. My father, ooooh boy my father. what a cunt. he has abused my bro, my oldest bro, and recently turned on me. My parents divorced, so I don't see him often but should see him every other weekend. I choose to never see him. He is abusive and he doesn't acknowledge it. He e-mailed my mom saying "he has this misguided perception that I'm abusive" nigga I'm not misguided. I'm so upset. The only people I can fuck with are my grandparents, my oldest brother who lives really fucking far away, and my step-dad. Every night at around 12:00 I sneak out and ride my skateboard for an hour or two to blow off steam without getting violent. The only person I can vent to is my girlfriend, and here, I guess. I can't even vent to her too much because she has so much on her plate already. Idk, homie. shits tough. I've been through the wringer so many times, I feel like I've been put in the dryer for 5 years straight.
