I feel out of place

With my parents both in the military I moved all over the United States always having to meet new people and make new friends. Ever since junior high my list of friends seemed to diminish as I moved from city to city. I still feel like I had a normal high school experience (even though I began at one and ended at another) having acquantences around school, a job, girlfriends, and "friends" from work or school that I would do things with.
Now I'm 21, graduated and going to college in the same area I graduated high school. I've lived here for several years now. I also have a part time job with coworkers I occasionally do things with. There's no one at my college I would consider more than an acquantence. While most people I meet are friendly, I never seem to connect with them, either I see them as someone I don't want to be around and distance myself from them, or they don't seem interested in my friendship.
I don't have what you would call close friends and I'm not close to my family. I feel out of place here and have felt this way for years. I've decided that if I feel out of place maybe I am so Ive decide to travel out of the country after this semester with hopes of finding a new place where I can call home...
Any thoughts or comments would be appreciated...
