Very sorry to hear that. I went through a similar thing basically due to my low self-esteem, I would hang out with anyone who would hang out with me. But they treated me like shit, and it took a while for me to figure that out. But now I have a rule I don’t hang out with people treat me like shit. It sounds pretty basic, and it is. Really examine how they treat you. I’m not saying you won’t be lonely, but you need to actively and I repeat -actively- seek out a new life and new friends. Good luck.
