Times are changing and I'm afraid

Lauren
I'm moving on to a new school this Saturday. I'm living there and this is the first time I'll ever be away from home for longer than a week. Me and my boyfriend of almost a year ended our relationship due to trust issues, constant arguments and mistakes made on both of our ends. He's at a school that's about an hour and a half away. As these times are changing all I want is to make it stop, I don't want to go anymore - I'm chickening out. I just wish my relationship could be good the way it was before and have him back in my life and us to not be so distant. I guess in all I'm just having a really hard time accepting this change. Does anyone have any advice as to how I can just man up, commit to this school and my choices and keep moving on?
