How to come out of depression?

Latel I've been depressed af.. I've trained myself to believe im not good enough.. For anybody. I literally have no friends, family won't listen and nobody wants me romanticly.. Just sexually. I kinda blame my dad for the way i let men manipulate me to have casual sex with them. Because he wasn't around my whole life and still till this day he doesn't hug me or tell me he loves me. And i feel nothing afterwards.. I just do it to feel wanted for the moment. I dont want to revert back to cutting myself but i literally have anxiety attacks when i think about how i will forever be alone. I dont feel im beautiful i just feel pointless.. Anybody can relate and or help me get out of this terrible state of mind
