I'm afriad to go away from home?

I live in AZ I am 19, with parents. I have a room with furniture and live in a az style town. I went to Joplin Missori, where tornado was, and towns around it I liked, While I was there I felt home. My best friend is still there. Pittsburg State University is right there in KS. I found a room mate, and I am able to support my self. I am moving the 5th and everyday I think, do I really want to move? Then a minute later, I do. I dont like the people here and is hot, and drive far to go places.. Its mainly the fact I can live on my own that makes me wanna go. Opinion?
