Go to the gym and get some muscles, also normal girls like muscles lol
And here in Israel if you don't get some confidence and go talk with a girl you like, most probably you'll never get a girl, and if you will, 90% she will be ugly lol
Just think like this:"I'll go talk to the girl, if she likes me I won the girl, if she doesn't and I just made fun of myself I don't give a shit, it was worth trying."
