The first year is rough. I suggest moving to an apartment or home that is close to your family. Then try to arrange a time, for the first 3 or 4 months, that a family member comes by, maybe just to watch tv, or eat lunch. Maybe try to do this 2-3 times a week. Then gradually cut back the time to 1-2 times a week. Then 2 or 3 times a month. once you are comfortable you can think about moving further away. It took me 3 years after i initially moved out of my parents house, before I could dream of moving to a new city. even then I came home 3-4 times a month, and had my family come visit me often. and even now I live 30 or so miles from my oldest sister. It's comforting to know someone is close.
Oh and one more thing. You will mess up. you will forget to pay a bill or realize cocktail cherries, mars bars and Mt. Dew are not a nutritious diet. etc etc. you will make mistakes and for a little while you are supposed to, it doesn't mean you are a failure or you can't live on your own. Just have enough common sense to ask for help, and try not to repeat the mistake.
you will do fine!
good luck
