Should I get a nose job?

I try so hard to accept myself, but I'm really looking into getting a nose job..My nose is killing my confidence and I feel if it were more narrow, I would look 20 times prettier. No one has ever said I have a big nose and I actually get comments all the time on how beautiful I am...but for some reason I feel it makes me ugly and that guys won't find me attractive at all. I always see the really cute guys I like with girlfriends that have nice, straight, narrow noses and it makes me feel like I'm never good enough.

I don't know. What do you think? Am I just overreacting and will I eventually get over this or is a nose job the way to go? (I'm 19)
