i wanna date someone. how can i change myself? 16F

Hi there, 16f. im the class clown and no ones ever really loved me except for 2 boys when I was really little and the pedophiles who only wanted my body. I'm also kind of ugly (i look really frumpy without makeup and I'm fat too at 145lbs and 5'8)

My mom wont really let me change my style because she thinks im slutty even tho i dress very baggy. how can i at least get someone to look at me? most boys find me really annoying.
