Am I too nice to be liked?

I have definately been there, this kind of sounds like high school. Don't take anything personally. From my experience it all disappears in college as you meet new people with your same interests. Just try to find new friends and don't be afraid to be yourself. If people do not like you for who you are its their loss, not yours. I don't remember a time I wasn't bullied during school, but it turned 180 degrees when I got to college. Just stick with your school work and forget about your peers, its not worth your time, and you do not need them.
