1) I work with an employment agency, and options for education and housing. I'm from a place that isn't here as well, so discussing things like that can help.
2) I can probably also help with a doctor. I know a few, and I can get you a hold of a few.
3) Peanut butter's got fats and protein. Not amazing, but it's totally a food. A lot of foods for people who have been starving use peanuts or dehydrated milk for the proteins.
4) Pretty sure that'd be a lot of sugar and caffeine. Not deadly, but not great. Would you be interested in some food related lessons? Cooking or just basic theories on nutrition from here?
5) The internet's a lot. I've been researching online security, and I scared a neighbor by trying to remember my IPBE / SOCKS and so on.
