Please tell me what to do guys....I'm sick and tired

So I'm 18 and I'm in middle of my finals and I didn't have time to clean my period underwear...not intentional, so mom once again was in the mood was an argument and she started speaking about this matter INFRONT of my 15 year old brother and so I started to lash out and misbehave and them my mom threw hot burning tea on me not to mention I am kinda used to this now my dad also hurts me if I don't listen emotionally and physically both like he even told me once that if I was a porn star no would buy me still (though I was wrong that time) but that made me completely hate him and get nightmares of him assaulting me not to mention I'm Muslim too, and I'm reaching my breaking point very quickly since this is not normal for Muslims, I am now so used to this but when they do all that they expect me to apologize to them (but after painful begging and them accepting my sorry they act normal like nothing happened don't get me wrong I have everything a 18 yo wants I have a ps5 2 tabs everything but I never feel happy since I always have to go through this again I was also once forced to stay on the cold marvel floor of my bathroom in extreme winters because I misbehaved to mom and she video called my dad (he works abroad and I was having a trauma response) that I was misbehaving and I was almost kicked out and this happened because I was caught playing a online game (royale high) ) just to put it out there I was also almost diagnosed with c PTSD but my parents took me out ,so tell me what the hell should I do I'm not allowed to have a phone ,no internet for friends,a camera in my room like what do I do.
