Do I Have a Right To Be Hurt?

I’m 20 years old and pregnant, and my mom had always treated me differently. She would call me fat, ugly, annoying, and more names but never treated my siblings that way. She also used to hit me and back me into corners so she could get on top of me and smack me without me running but she hasn’t ever hit my siblings. I’m one of the older ones, and my older brother and I grew up around extreme drug/alcohol use because of my dad plus we watched my mom get abused. We weren’t difficult but grew up with mental illnesses. I attempted suicide a lot as a teenager and my mom would just say I don’t have a REAL problem like my brother because he had autism and I just had depression and anxiety. She used to hit me when she found out I tried to kill myself. One time she lied and told me my dad didn’t want to see me in the hospital because nobody wanted me alive anyways. Now I just hate myself and I feel so angry all the time because I have really tried my whole life to please her and make her happy but it was never enough, I became so depressed and wouldn’t go to school so she would physically attack me every day for it. Most of her hurting me was because i was depressed. I told a therapist but they just said it’s normal for single parents to be stressed out and I need to cope better. I never talked about it again because it felt like anyone I told shut me down unless it was one of my friends from school. Am I right to be hurt? I have brought it up to her and she just tells me I’m disrespectful and that I’m a liar. My siblings also defend her and say I was just a difficult kid and deserved it. I just feel so hurt and angry still.
