family issues .. help !

hey ladies, hope yall are doing well and taking care of yourself ! if you can give me any kind of advice just comment below, please be nice. im really needing some advice, thank you !

so, when i was 8 years old my mum went to jail and i moved in with my dad. i basically lived with my grandparents and mum full time and i felt so loved and cared for. moving in my with my dad and his gf at the time was really hard for me. i hated it there. i had an ipod and would download facebook to talk to my grandparents and my dad found out after i did it two times and grounded me for almost year both times. i would write in a journal about how i got treated there because my dad and i just didnt get along. it was constant arguing just about everyday. and he found it and would go through my room and all my stuff and ruin my room and make me clean it up aftee. fast forward to when i was 13 .. my dad and his new gf treated me even worse. she would always say i need makeup and bring me down and my dad and i still argued. one day i was so so upset, i told them i wanted to kill myself and they sat there and laughed at me and told me to go ahead. on my 13th birthday i self harmed for the first time which was a few days aftee they said that to me. i took my dad to court so my grandparents could get custody of me at 14, the judge said my cuts werent deep enough and told my dad to take me to counseling. he took me once. everyday was a living hell and still is. he threatened to ground me because i was self harming instead of asking if i was okay or anything. when i was 15 he got married to a different girl and we moved in with her. it was tough on me. ive always gotten treated so differently. im 16 now and the same stuff is still happening. i remember my dad yelling at me for wanting to stay home from school because i felt sick and that turned into him yelling at me about how badly i make him feel as a parent and im too stressful for him. he will laugh at what i eat and when i do which led to me having an eating disorder for a few months. my dad has always said im overreacting and faking my mental and physical pain. he was refused me counseling and gotten so mad at me for telling my doctor physical pain i had because he didnt wanna pay the money. recently he has gotten mad at me for working hours that are unconvenient for him after i asked my step mum if i could work those hours, she said yes. a few days ago, i asked to go on a run with a friend because ive been so upsets due to my little sister moving to a different state and stuff at work so ive been in my room crying a lot. he said no and i said okay and he said "i mean what makes you think that's okay at this time" and was getting stern and i said "dad idk i didnt think its be a big deal because i thought jayde was walked around later than this" (it was 8pm, jayde is my step sister) he said no, i was wrong and i make him feel like a bad parent and everything he does gets blown up in his face for how he treats me and his tired of it. i had a panic attack and was crying so much so i called my bf and told him what happened. apparently my step mum overheard and was extremely mad at me. today after i got off work, she told me i was lying about how i get treated here and i tell myself that i have such a bad life after i dont. she said i was disrespectful and they dont deserve it. my doctor told them she thinks i should live somewhere else and it made her even more mad. she said shes going to sit down with me, her, my dad, grandparents and mum, and my bfs parents and tell them i have been lying. my bf and his parents say they believe me because ive been struggling with this ever since i met them and they know im not just pulling stories outta my ass lol. my mum and grandparents also believe me which is good. i was so worried they wouldn't believe me because im a "kid". im stuck, scared and confused. any kind of advice would help me. i just wanna get outta here ..

** also, i didnt explain how i get treated differently. but my step sisters and step mum have all gotten offered counseling and are in counseling except my one step sister (i have 2) after i asked and they never got me it til my doctor called my dad and told him multiple times. he called two days ago finally and said itll take 2-3 weeks. on top of that, if any of them are upset or going through something. they rush to them and love them and support them with open arms. but everytime i have a panic attack, they ignore me or get mad at me for crying and say im overreacting. when i was sexually harrassed many times, my dad said it was my fault .. and at work i recently had a stalker kinda and him and my step mum laughed at me but when my steo sister had something happen to her, they took it so serious (as it should) and would always ask if shes okay. my little step sister was diagnosed with pandas disorder and they got her everything she needed (as they should) but they tell me im overreacting and faking my severe headaches (which im going to a neurologist about) and that im overreacting about my ocd and anxiety.

this is just some of it but mainly whats happened since i moved after their marriage
