My heart goes out to you, because I see you really struggling with and overthingking your decision, but rest assured that you made the right decision for yourself. As wonderful as Rice is, U of Tx has a great rep throughout the US. More people have heard of it over Rice. Fit is really important in my opinion, and you chose a school that you felt was the right fit for you. That was smart. Relax, and get excited about the next 4 yrs, which will be everything you were probably hoping for in the college experience
