Hey, Dev, how brave of you! I think, no matter what, it's going to be a bit scary since it's "new". Sometimes I can help my anxiety by reframing what I'm doing as "exciting" rather than "scary"? The feelings can be almost the same :-) Look forward to the adventure and opportunities rather than the worries? There will be classes to sit in and you are bound to like some/meet a student or two to say "Hi" to along the way. Think of how many friends you have now, why should you have less at a new place?

I think it's great you have one friend going with you; suggest that the two of you go out together occasionally to things on campus/in town, etc. where you can maybe meet other people. I always find it easier with a friend around too.

The biggest thing that helps me in a new place is remembering it takes time for it to be "my" place. When I start a new job, it takes me six months to get use to the job and people! I know that about myself so I give myself time.
