I need a mothers advice?

I'm 23 and a mom of a 5 year old. You are just going to have to ignore them. If you know they are wrong, then...they are wrong. They aren't worth the stress or anything. Weird or not...no one can litterally be considered "normal" unless they are in their own clique or group, and they call themself normal. Everyone is weird in their own way lol. It sounds like the rest of the 13 that you said no to are just jealous jerks. They aren't worth your time, and I promise you that one day they will regret it, and then forget about it. They wanted you, and you hurt their ego, which is why they're saying those things. Life goes on, and you'll graduate and forget about those things. Just ignore them.
