Fix my depression? No parents wont help?

So yeaterday my gf dumped me again... It hit me hard. Cause for once in my life i actually felt someone loved me. I had a mom and a dad. Dad used me to cheat on my mom when i was about 4 they split up when i hit 5. My dads side of the family hated me because of the stuff my sister said about my mom. M moms side of the family is racist to mexicans. So my mom never wanted me. Always calling me worthless. N telling her friends i already had two kids i didnt want another. Dad seez me as a failure n worthless. So i never had anyone to love me as i grew up. I always had depression. But my mom dusnt care to try to fix it. Or my dad. My sister use to always do wat a sister duz n beat the younger brother. N since i dont hit girls. I had some really nasty welts n bruises. Untill she did her own thang. Other brother n sister left me when i was abiut 7 n moved to different states. So i had no one. And every since my gf dumped me yesterday. Ive tried to kill myself. I took alota anxiety medication. N i dont remeber anything after that. I woke up this morning. N i feel dead. I dont wanna be alive. Gf dumped memcause i questioned stuff abiut this guy that kept kissing her. She said i didnt have tomfeel the pain anymore n left me. I love her. I really do. N ima beat the fk outa that guy today. Someone just help me...
