There is no should and shouldn't be anything, you are what you are and you should accept that & try and find a solution. I think maybe you need to try and enjoy your experience at college. I know sometimes it's hard to go out of your comfort zone especially when you are missing your boyfriend, maybe you should set yourself some goals? Or try and get involved in more activities and meet new people and at the same time take your mind off things a bit as well.
I think you should definitley try counselling, it could be really good for you.
I think you should try and see your relationship with your boyfriend in a different way, instead of feeling sad that you don't see him often and can only communicate be email, try thinking positively that you have met a guy that you love and that he feels the same.
