Highschool problem please help (10 pts to most helpful)?

I'm intimidated by uppperclmen. I'm a freshman and I'm intimidated by sophmores, juniors, and seniors. They just freak me out! They scare me because they are older. I have a few upperclmen in my study hall, they always try to socialize with me but I always just move away. We have a new student that a sophmore, that likes me but I don't like her because she's a sophmore. Is that a good reason not to like someone? They hate me because I'm a freshman, I hate them because they are upperclmen. Am I being unfair? I mean they kind of started it with the freshman hazing.
