How am I supposed to overcome this or have I reached the end of my life?

I'm not ugly but I don't really fall in love much and if I do it always ends with drama. 2/3 ended in severe drama. Everyone in my life has become an enemy and I believe that this is gods way of punishing me for all the mistakes I made. I don't hurt people but my mistakes were out of pure ignorance because i genuinely didn't know certain pieces of information and this has ruined my life. I know that everyone gets lonely but I don't have a group of friends. I got set up by people I knew a decade plus they tried taking my life cause I was talking to a female they liked but they didn't know how to go about it so they creeped her out. I'm 18, 19 in September and I know I'm not gonna live much longer. Not that many people like me if there's even someone who doesn't see me as walking cancer. I don't think I'm a bad guy don't do drugs nor do I beat women my intelligence is actually underrated because I'm a minority. I know make people laugh I saw the look on this girls eyes when I was telling a story about my life and she was laughing really hard. I'm not threatning either but I feel like my wellbeing is threatened everyday. If it weren't for high school I'd be isolated into this house. Although I've gotten further than most people would in terms of grasping my dreams I also feel them slipping away. I am alone and no one is willing to help this doesn't make them bad people. But I won't live to have a wife or kids. women can do better than someone like me.
