Am I in a rut? Things are just soooooooo unbearable :(?

All my friends are leaving for college ( I have to stay back because i was very lazy in school and need to make it up) my girlfriend of two years is great and all. But I think she's very emotionally abusive and uncompromising even to the point of making threats and saying incredibly hurtful things to upset me, even though I just want to talk it through and fix things :( I used to be really popular but now it seems like I'm all alone. My mom and I have never getting along and she refuses to go to court appointed anger management and k haven't seen my dad In years. Can someone just tell me if this is part of getting older ( just turned 18) or is there something better out there. I don't think I'm complicated. I just want to have friends around and people that will listen, and I want to find a soulmate. Someone I can look after and love and share my whole world with. I guess im asking... Am I being unrealistic? Or whiny? Any advice? I dunno just some kinda response I guess. Thanks for reading everyone (p.s please excuse my typos as I am on my phone lol)
