I'll try to give as much backstory as I can. So my mom has BPD, she cheated on my dad and I see her like once a year. She's never interested in what I have going on, unless it means she can yell at someone. 

I've since only considered my Dad my only parent. But within 4 months of the divorce he me a new woman. She moved in way to quickly, and thus began her control over everyone in the house. She verbally and emotionally abused from the age of 10. Finally, after 10 years my Dad left her. I guess all it took was my 6 months of recovery after cutting myself and damaging a nerve in my second year of college. Not 1 week after she left and I moved back in, he met a new woman. I had to help him clean the house and prepare it for her arrival. Money's been tight so I've been eating ramen, and putting aside what I want. He said his back hurt yesterday, so he couldn't help me clean FOR HER. Then he goes out and spends $400 on groceries, decorations, and other things to impress HER. And then keeps me up all night fucking her. He even offered her a house key on the third date! Now today, his back hurts too much to get me dinner, and I'm left with nothing. I'm too broke to buy anything since I just got my first job since the damage from cutting. I just wish for once he would be happy with just his daughter to spend time with, and  not need a girlfriend. 

I was just recently diagnosed, and he keeps holding it against me instead of listening.
