I'm nervous about transferring colleges?

Last year, I went to a private college that was about an hour and a half away from my house. Simply put, I hated it. I missed my friends from home, I missed my parents, and although I made some friends, I didn't really form deep connections with any of them. I came home every chance I got and dreaded going back at the end of breaks. This year, I am transferring to a public school in another state that is about five hours away from my house. I decided to transfer here because it is a reputable school, is in a location that has tropical, warm weather, has a great pre med program (I want to be a doctor), and I have a few friends who already go here (even though the school is pretty far away. Well as the next school year approaches, I am having second thoughts and wondering if I am making the right decision. I'm afraid I will be just as miserable there as I was at the college I attended this year and that I will miss home just as much. I also feel guilty for leaving my parents. Although they support my decision to attend this school, I know they are going to miss me terribly, and I feel horribly about that. Additionally, I will miss them terribly.Like I said before, I have some good friends who go to this school, but what if they are different at school, and what if I don't make any new friends? Is it hard to make friends as a transfer student? Sorry... I just bombarded everyone with a million questions. I am just really nervous about the future.
