I need some support..

I’m just going to get right to it. I have like zero friends and I hugely rely on my amazing boyfriend, which isn’t good because he can’t always be there. As much as he wants to be. Me and him are around 3 months in to our relationship. But I’ve always been depressed. It’s almost like when I turned 14 a switch clicked and I just couldn’t get happy anymore. After that switch a lot happened. My grandpas on both sides of my family died. I figured out before my parents got divorced my dad cheated on my mom. Then recently he got married to my best friends mom. I’ve realized I’m bisexual and I live in a homophobic family.Recently I got out of an through an awful situation with the boyfriend I had (before this one) for about two years. He emotionally abused me and forced me to have sex with him. I’ve been messed up ever since. I can’t stop feeling worthless. My new boyfriend tries to help. He wants so bad for me to be happy. How do I get out of this hole I dug myself into? I literally feel like if I disappeared it would benefit everyone else.
