Am I overreacting? Please I just want a friend

My bf check came late and he’s been paying my phone bill which I’m grateful for and his check came late so my mom paid for it. It was 200 which was INSANE but I was grateful she paid for it and today she asked me about the other half because she said we could give her half and before I lost my job i literally was giving her money back to back. I was paying her bills before mines and I couldn’t pay for mines which made my credit bad. Around the same time she wouldn’t let drive her car and I was well over 18 she let my siblings with no license drive her car but I was actually giving her half payments every 2 weeks even when I started college I gave her all my school money which was well over 4,000 for each semester so for about 2 years I was giving her all my school money to help pay bills and buy her things and then I got a job and since I was basically working 50 hours a week I couldn’t focus on school and ocd I was going crazy. I couldn’t even buy simple things for myself with out her judging me I couldn’t have sweets or meals then I was too fat. I understand paying somebody back but I literally gave this women all I could FOR HER she could atleast let this slide. I didn’t ask to be born into a family with multiple people and that made us go into low income, I had to sleep on the couch while my sister had a room, mind you I’m the youngest sister. I barely had clothes, I had a clear bucket of clothes that they would constantly take. My mom has hated me for so long, I couldn’t even ask for basic needs without her getting bad at me like soap “why everytime I need something you need something” I wasn’t even a problem child like my other siblings I just talk too much and make simple mistakes like being clumsy. My parents hated me so much if my siblings did something stupid and I’m minded my business like watching tv they would come and hit me and say “just incase” and they completely deny everything. I’ve always been a mommas girl and i finally asked why she hit me so much and she said it’s because I’m too clingy DUHHH as a child who wouldn’t be to their mother??? I just wanted to vent because she knows I moved out because my family expects so much out of me. I just left the mental hospital, I’m trying the hardest I can.
