Found a place to rent!

There is someone close to campus who has a studio apartment for rent! I decided to rent it! I feel really sad all of a sudden though and kind of guilty........I hope I am doing the right thing? What if my mom needs me? what if I get sick? I have all these emotions going through my head but I know I am doing the right thing. There isn't really a place to do laundry but I can go to the laundromat or something, or even do laundry at a person's house. God this is really a gut wrenching feeling in a way, but I don't plan on staying away 24-7. And I'm gone so much that I really need a place here.....
