Hard time leaving...

I moved out of what was basically my home for 3 years yesterday, aka my dorm room at college. As much as I did not want to be there, I realized right when I left how much I was going to miss it. Not only that, but my roommates who I have been living with for 3 years. They've always been there for me, & put me in a good mood when I was upset. For next year, were all living in separate places. I am moving back home & commuting to college 3 times a week. It makes me sad that I'm most likely not going to hang out with them all the time anymore. I've never really had any "true" friends in high school, but my roomies are to me. I'm just so terrified I'll never hang out with them again, & be so lonely sitting at home by myself. I know it sounds so stupid, but I really couldn't sleep last night because of how sad I am, cried this morning to my bf, & am just super sad about the whole situation. What do I do. 😔
