I transferred from a major university to a satellite school of an even bigger university, although this school itself is smaller than my high school, I think. Anyway,
A lot of people asked me why I transferred, and I never knew what to tell them, but really, the only real reason I transferred was because I felt God wanted me to. And since he was asking me to leave everything familiar to go to a new place (300 miles away? something like that...I dont know), he took care of me. Before I went down there, he provided me with a familiar face, which was someone I NEVER would have expected to see, and then he gave me two really good roommates and another great friend.
If you're worried about friends, I would really just pray that God would provide, yknow?
As for the transfer itself, I was really nervous, but looking back, I kinda miss that time of my life. It was all pretty exciting, cause I was stepping out totally on my own, going to a totally new place, meeting new people...it was really adventurous, and I do kinda miss that period. But I do wish you all the luck with your transfer, friend, and I sincerely hope it goes as smoothly as mine did.
