Just remember, Rome wasnt built overnight. Its going to take time to find your spot, to get yourself settled. Go in knowing that things arent instant. Go in remembering this is education, not popularity contest. Go in knowing, you are coming in with more experience than a lot of people there (You’ve been somewhere else, which is why you’re there now. That will give you something to talk about.)

As for sleeping, just take a bath. Listen to some music. If it helps, write down the things you’re worried about (it’ll be real funny to look back at them at the end of the year and realize how different you’re feeeling now as compared to then). Go to bed early, expect to do some tossing and turning. But basically, dont worry about it. You’ll be fine!!
