Since everyone is already saying how pretty you are, lol, I'll say again that you are pretty, and tell you how I finally stopped seeing myself as ugly

Well, when I look around, I see alot of people who are prettier than me. But I think about how lucky I am that atleast I'm healthy, I'm at a good weight, other people like my hair even if I hate it.. , and I pick certain features that I like about myself

Try it, you are so pretty, I'm sure if you just think about how lucky you are, and that others think you are good looking, that you will see yourself as pretty too! You aren't overweight, you have great hair, a very pretty face; try and think of more things; You'll see

And although I don't think you are too young to date, I believe that you are very right that a relationship can't be cherished until someone is more mature. I mean the guys of course
