dannycopper: I was in a club recently and approached a nice girl to strike up a conversation to which i was told "Go away ugly" i know you should not take stuff like that to heart, but it really hurt and kinda messed me up. I was finally starting to feel confident in myself for the first time in my life
You need to grow a thicker skin and believe totally in yourself. You'll probably be called worse things than this before your lifes over. If there's one thing I've learn't in my life, it's that there is always someone ready to try and put us down.
A similar thing happened to my son though a couple of years ago when he was your age. Him and his then girlfriend were walking through a shopping centre when suddenly 3 girls aged about 18 started laughing at his hair and acne and calling him ugly. Which probably wasn't the wisest thing they ever did as his girlfriend has a temper straight out of hell and was very protective of my son when she was dating him
Anyway, she went verbally mad at the three girls and threatened to throw them down the escalator and they all ended up in tears

and not tears of laughter either
So, I do think karma does work and one day the girl who hurt you will get a taste of her own medicine, one way or another
