I don't have much to add to the good advice here. Make sure you get some food (if you absolutely have to, you can buy more at the overpriced gas station store, and of course you can order pizza, and maybe Chinese or anything else you have around there). I hope you can get through to your parents and tell them that you need them right now. And if you have any friends with cars (or friends' friends with cars) you can just let them know that you'd like to go grocery shopping when they go, if there's room--then you're not putting them out at all. Hope things look up for you soon; if there's anything I can do (though I'm about as far away from Maine as one can get) let me know!
