Is this ok?

Rachel

I’m 11 and weigh 142 should I be worried. My doctor says I’m completely fine but I feel like I’m too fat for my age. I mean some kids are WAY fatter than me but I still want to lose weight. I wish I could fit in my best friends clothing. She is 12 and wears a large in kids for Under Armour sweatshirts. I’m a medium to large in Under Armour I’m women’s. I feel fat. What are some good ways to lose weight???
