I feel too fat..

Kara
I'm 135 pounds and I'm 5ft2 age 13. I feel like I'm way too fat. All of my friends are less than 100 pounds and it makes me super insecure about my weight when they talk about it. I'm scared to see my family each time I visit them because they pressured my cousin to go anorexic so she could be skinnier. Any advice? Am I too fat? Do I need to lose weight?
