Ps when I refer to my dad I mean my step dad, my real dad hasn't been in my life for awhile.

So im 14 and a freshman in High-school and my school is still doing online school. I moved down to my grandparents house at the beginning of the year because living with my parents was horrible for my already bad mental health and my parents are not good for each other, screaming at each other, fighting all the time (it often gets physical), and I was constantly getting in trouble for being myself and it got really bad on new years, so bad in fact that I nearly lost my phone to my drunk dad trying to throw my phone off the balcony because he had drunkly subtly threatened my sister and I yelled at him then he grabbed my by the collar (breaking the necklace that I used for my religion in the process, I never saw it again) and I slapped him because I don't have a good history of people being in my face. My dad would get in my face all the time throughout my childhood, I was bullied immensely as a child, ive been through a bunch of different types of sexual assault were the person would get in my face, and as a person who suffers from DID( dissociative identity disorder) one of my headmates hate him and is really protective of the body for reasons above. Then after getting my phone back and going through the rest of the night with my mom and my sister while the situation continually got worse and eventually my mom decided to send me to live with my grandparents for awhile. This was the best thing that had happened to me in a good while because I can finally express my emotions without being berated and punished. Then while doing school I had gotten my period which always makes me faint(more than usual), super tired, nauseous, i have a really heavy flow(I've bled through a 12 hour pad in 3 hours and in 5 hours before), etc. I could barely function on my period and I missed quite a few assignments since I was barely awake at all during that week. Now I have to make up these assignments and get my grades back up or I have to move back with my parents which would be really really really bad. I'm so stressed I feel trapped and I feel so tired and now my school is fucking up my attendance and saying I didn't go to any of my classes even though I did and I feel like giving up. I'm on antidepressants but my parents make me so depressed and want to hurt myself, it was so hard not to self harm with them but while I have been here I haven't wanted to do it at all until my parents started screaming at me over the phone and making me feel like shit. I tried explaining to my mom why I was missing assignments but she screamed at me and told me that my period wasn't an excuse and that hers is worse and I can't use my period as an excuse yatayata. She is always invalidating my experiences and my parents always tell me that im being over dramatic and making up lies to my doctors. I have never seen a gynecologist and I started my period when I was 8 and I have horrible debilitating period. I have begged to see the gyno and I have never been able to go, I have to fight just to see the doctor, i haven't seen the dentist in years, and it took my a week to get my parents to take me to the doctor when i had a painful middle ear infection that started to make me lose hearing in that ear for the time being. I have to fight to see anyone. I have been fainting for 3 years straight, my parents threatened to take me out of school if I didn't stop, I had to have an ambulance come to my school one time because my period made me dehydrated and it made me faint way more and because it made me so nauseous I barely ate so they had to give me fluids and food because my blood sugar was dropping so quickly due to the lack of food. I have been to the doctors about it twice within the last 3 years and it took me mentioning the fact that my heart randomly spikes then drops and I get dizzy and it happens out of nowhere to my psychiatrist for her to tell me that she suspects I might have a heart condition. A FUCKING HEART CONDITION! I'm a very mentally ill person and my parents make my mental health worse. My girlfriend hates them so much, I get in trouble for no reason and my own dad refuses to believe that im a Lesbian because I "dated" boys before but when that gets brought up he says that I didn't actually date them. Then when I bring up the abuse my friends has gone through by the hands of their parents my dad just tells me "well why haven't you called cps if it's so bad" and I always tell him "because I don't believe in them they don't work" and he gets annoying and he says "well it didn't work for us because we aren't abusive to you" . Then anytime I've ever tried to tell them they are being abusive they always say "well we can't be because we aren't hitting you". I'm exhausted and my girlfriend lives in a different state than I do so we have to do long distance

Not to mention I get cramps so painful that if passed out from the pain before and I always have to take pain killers when I have them or I won't be able to do anything and all just cry or pass out or just sit there. I should have seen the gyno a long time ago, especially because period issues run in the family and after I had my first period I had to go to the emergency room because I was puking for hours without stopping and eventually I didn't even puke up bile anymore
