Hey, i have low confidence and think im ugly!?

Hey guys this all started in year 7 when i was going out with a chav and she said i was ugly and she dumped me and said she was desperate, anyway im in year 11 now and went to flamingo land a couple of days earlier and i was standing in a queue for kumali by my self when a few les said to me do you want to go out? and i ingnored them until i finally said i have a girlfriend (for a joke which made it worse!) and one of them said ewww who would want to go out with you! And it made me upset for the rest of the day, and now my friend met new friends to meet up and they were 2 boys and a girl and my friends (girls) got into them straight away and my friend asked the girl to give me a chance and she said i was ugly and she didnt think i heard but i heard it clear! And my friends are now saying i need to get out more and you will evantually find the right girl but in my opinion is never going to happen. AHH! i cant post a picture because im unable to.
