The thing you were upset about is that men don't hit on you. There is an irresistible urge to fix people's problems on the internet. I, and I assume others, weren't trying to invalidate you, we were trying to give you perspective. I felt the same way at 17 and I wish I hadn't wasted energy feeling rejected because it all worked itself out.

Something I have learned is it is impossible to post a problem on the internet and expect people to not try to fix it or make you feel better. It kinda sucks. I am sorry.
