huuuuuge prolem, need help.

help me out here,

i have a huuuuge crush on one of my close friends, but i don't know how to tell them, because they're slightly older than me and i have a feeling they like one of our friend more than they like me,
and i'm just confused about what to do about it,
because the age difference in kind of a problem, but they're aren't like, 10 years older then me, don't worry.
and we don't even ANYWHERE near each other, and i was thinking of going to visit them next summer.
and it's kind of weird, cause i doubt they feel the same as i do.
urgh, life sucks.
ahaha i sounds like a friggin' emo lolz.

help me?
