My mother is crazy af

Okay so I'm not in state of typing long ass para but I need to vent.
My mum saw porn site open on her phone (i use her phone) and it was open as i wanted to masturbate and sleep after a long night of studying. and Everywhere on internet it is said that masturbation isn't wrong. So when she asked me I bluntly said "to masturbate". And the way she lost her temper called me names and even hit me several times with a pvc pipe. I got really angry as I'm not wrong for masturbating and honestly I fell asleep while scrolling as i was tired af. man she is didn't react this way when dad graped and SAd me for 3+ years but blamed me. Now she said she'll not let me study. I'm a NEET and NDA aspirant I was preparing for JEE too but due to lack of time and no mentorship I gave it up last night after A long discussion with a senior and when she found I called a senior she said i was dirty talking with him. Two days she called my 16yr old female friend, a characterless (wh-re and sl-t) girl. Just cuz she lived in hostel for 3 yrs. She is totally against sex, and on other hand my dad has high drive. which i also got and After those 3 yrs i turned hypersexual. I control it well but now I don't know what to do, I feel like giving up everything because I did everything to not burden them and they ignore it all just over masturbation and she tagged all my long night study sessions in 10-15 degree C cold as "ik what kinda things u do at nights"
