I'm 12 and I'm 5'4. I weigh 135 pounds. I feel fat and I want to try and lost weight. I don't eat fast food a lot. I walk a lot but I still feel fat. My sister is older than me but I'm fatter. I want to be skinny and not feel ashamed of myself. One of my friends throw up their food and are constantly sick. She stopped after her therapist told her. I haven't and I won't do that. I still want to lose weight before the summer ends. Some of my friends tell me that I'm skinny or skinnier that them. But I just don't feel confident in my body. If anyone has tips please tell me.
