Ima stop eating

My mom and brothers make fun of my thighs I'm the only one in the family that has big thighs... I'm 4'7 and only 15 and my thighs I need 3 hands to go completely around them... Will only drinking water help me lose some weight? I've lost a lot of weight before and collapsed on my way to school before but I just want to lose some weight not all of it...
