VERY LONG RANT/ SO annoyed with me venting

I've had an extremely hard life. Both of my parents are drug addicts that were never married, I've never seen them together or in healthy relationships. I was molested by my mothers boyfriend at 6 years old and bounced around from relative to relative. My dad got married to a horrible verbally abusive and slightly physically abusive bible thumping hypocrite who made my life a living hell. My clothes were always worn down and either too big or too small. My mother tried to kill herself multiple times over the years and blamed it on me. I barely graduated from highschool because of severe depression from being raped at 17 and bullying. I was in a major car accident last year and now have a permanently fucked up spine and will be in pain for the rest of my life. My dad took away my health insurance for no reason, called me a slut for moving in with my boyfriend who I've been with for 2 years. I have PCOS and hypoactive thyroidism as well as my back problems so I NEED to see a doctor regularly and pay for prescriptions, so now I'm very stressed about money. My mother finally reached out to me and apologized, I sent her this crazy long text about how I felt about her and she still hasn't replied so my anxiety is racing. I had to give my dog to my boyfriends parents because we couldn't afford her anymore, and their youngest daughter (4 years old) told me yesterday that her mom (my boyfriends mom) told her I abandoned the dog, who I love deeply. I just vented all of this to my boyfriend and he calmed me down at first, and the second I mentioned I wanted to go to therapy he just said I was dramatic and got all pissy with me. I told him he makes me not even want to tell him what's bothering me and he said it's always the same shit with me and I need to just get over it. I can't work yet because of my back, I have no car because it was totaled, I have no family, no dog, I don't even have any fucking clothes because I've gained so much weight after the accident. I'm just so miserable and alone right now and I don't know how to get out of this slump. I feel worthless and broken down. I'm only 19 but I just feel so tired. I told myself I wouldn't play the victim anymore, but after the accident I feel like life is laughing in my face while it kicks me when I'm already down.
