Boys are never interested in me

For so long I’ve noticed how my friends go through boyfriends and I struggle to keep a boy interested in me. I am the biggest of my group, all my friends are slim and beautiful and it really affects me.

Tonight I was at the pub with 2 friends when 2 boys came up and started flirting with them, I was the odd one out who no boy was interested in and it really upset me! Things like this, and when we did a group (boys + girls) awards I got no votes for being prettiest but all the other girls got at least one.

My confidence is constantly knocked down and I’m really struggling with it. I try to lose weight but end up binging on food after time, I don’t know how to make myself cope with being the ugly friend.
