I am pretty anxious to leave my parents' house so I can't say I know how you feel. But hey it sounds really hard so here's a big ! It may help if you can Skype/FaceTime your family and get them to mail you stuff (snail mail, not email). I think having some things that remind you of home can really be a huge anchor when you're super homesick. I miss my T a lot when I'm not seeing her and I deal by looking at her photo or listening to voice memos.
