I'm not giving you a numeric score, you're 15.
You're not ugly, at all.
"ugly" is a standard put down people use on women (that or slut, basically). It's kind of remarkable the extent to which insults show deep values in society. Women are valued for being pretty, young, and sexually chaste. So the stock insults for women are about her looks, age, or sexual promiscuity thrown in. (Along with bitch, if they are 'too emotional'). Men by contrast are valued for power, physical courage and what they can accomplish, so the insults thrown at men are about being a wuss, loser, suck or a 'pathetic virgin'.
Nobody should take any of those insults seriously, since they are just the most obvious things thrown out to hurt.3

I'm sorry, but honestly having a bunch of strangers tell you if you're attractive or not is not going to help your self esteem. You need to look in yourself for that. Figure out what it is about yourself that you don't like and either find the beauty in it or work to fix whatever the problem is2
