Please help me i feel alone and i don't know what to do!?

my friends were fighting and putting me in the middle of it and now they're all turning on me together and talking about me behind my back and they think i've been doing the same to them which i haven't. and, my parents are always fighting, but it just keeps getting worse and worse. tonight my dad called me downstairs to take doxycycline (which my dermatologist prescribed) but my mom knows it makes me pretty sick so she was defending me and telling him not to make me take it. but i took it anyway because i was scared my dad would be mad. after i went back upstairs my dad started yelling at my mom and they started fighting and his voice kept getting louder and louder and i heard him walking over to her and i think he bent over her and she said "if you even touch me we'll see what happens" and my dad said something i couldn't make out and then stomped back into his room. he didn't hit her but i was so scared he would. he usually never does anything that bad. there was only one other occasion where their fighting got this bad, when i was about 5 and he basically chased her around the house yelling at her and she locked herself out on the balcony. but it constantly feels like my dad doesn't like me and he wants a different daughter and he's disappointed in me. i feel so alone, and i have no one to turn to. anyone i used to me close enough with to talk to about this has now turned their back on me. this guy i love so much, who i had been friends with for years, and who loved me to, he's so perfect..well he doesnt care about me anymore and ever since i realized that i've been trying to get over him but truth is it's bringing me down. i don't know who to turn to. i don't self harm and i don't want to i know life is worth living and things will get better but right now i'm just overwhelmed and i don't know what to do. thank you.
