Feeling trapped

I’ve never actually done anything like this before so sorry if this is the wrong place for this.
Things have been gradually getting worse for me and for a while now I’ve been feeling like there isn’t a way out other than to take my life. This past year has been pretty hard; I’m studying a really difficult degree at a competitive university, as well as living in a house of 6 boys who have chosen to target me… They’ve spent the past year playing loud music at ridiculous hours, playing drums in the morning, deliberately slamming all the doors in the house because they know I dont like it and creating confrontations out of nothing constantly. They’ve threatened me. I barely slept this whole year and have felt uncomfortable, lonely and frightened in my own house.
At the same time a bunch of my friends turned out to think I wasn’t as intelligent or hardworking as they are and decided to turn against me because of it. My family moved house to merge with another family in an area miles away from anyone I know; nobody wants to travel to see me. I had to leave my job behind.
Recently my boyfriend left me because I was beginning to feel suicidal. I turned for him for help and he broke up with me on Facebook because ‘he wasn’t coping and his dad thought he needed to seek help for depression’. The irony actually hurts. There was a lot of making up and breaking up, conversations and lies from him along the way; its been dragged out over the space of a month. He kept me thinking there was hope for us when there wasnt. He couldnt just say ‘no’. I sent him an occasionally nice message and I’d already bought his birthday gift months ago, so sent that too. Not a word in reply. He wont give me closure. He wont explain to me why he left me. It hurts so much. He was my best friend for seven years and he has completely cut me out of his life at a time when I am vulnerable. I love him so much and this is killing me.
I’ve had several breakdowns, such high anxiety and low mood…been to three different hospitals in the middle of the night on four occasions, seen countless psychs and tried different meds. All in the space of a month. I’ve had depression/suicidal thoughts before; I grew up in a household where my mother neglected us… No food, no washing, no heating – just drugs, young men and watching her get beaten up every week. Depression runs in my family so I feel like I cant escape the cycle. I spent my childhood being constantly bullied. An ex used to psychologically and physically abuse me.
I feel like there is no hope for me. My life is a constant cycle of horrible events. I want it all to stop. My family would be so angry and disappointed but I am a burden to them. I dont want to hurt them but I cant take feeling like this anymore.
