<human>: I've known my SO for a few years now, and we previously dated for a year and a half. Now, we've been together for about three months, and it's been long distance ever since we've met. I currently live at home in a really small town, finishing up high school. This is really tough on me since all of my friends have gone on to post-secondary, and it gets really lonely without anybody around. Also, I really hate my living situation, as my family is unbearable to live with 9/10. Without giving my life story: I can't trust my Mom, her boyfriend and his kids are really messy, annoying, and disrespectful, and, in general, everyone is pretty insufferable. I'm pretty certain my family is the main reasoning behind my hostility. I really don't have any other options here other than simply waiting to go to college next fall.

When my SO and I argue, it's usually over nothing devastating, although sometimes it feels like arguments materialize over nothing at all. Silly spats can blow up easily sometimes, and we'll go through the motions. However, even when he apologizes, sometimes I simply can't forgive him. I honestly could not tell you why. I just can't help but continue to be very angry/upset about whatever it was and I just can't let it go. I know it's wrong, but in the moment I just feel really overwhelmed by it. I just don't know what to do. 

I'm going to try to get back into therapy (Formerly not intended for anger management purposes, but for depression and anxiety issues) because it's hard to talk to people since none of my friends are really around and even thinking about my family/the people living in this house makes my blood pressure rise.

Does anyone have any suggestions for me in terms of how I should deal with all of this?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I can't seem to let go of my anger involving my SO, and I feel as though my living situation is part of the problem. Help?
