i don’t like who i am

i am almost 15 and i don’t like who i am. I have side bibs and my stomach has some jiggle. i am naturally larger because i have big bones. my sister is a literal twig she is a runner. i don’t workout much because i am not motivated to do it by myself. i am constantly comparing myself to the people around me who are mostly skinny. last night i went to my mom crying saying i want to go to crossfit because i don’t like the way i look. i know that i am never going to be supermodel skinny but i want to get shape and lose some of my fat. i just want to turn my life around and eat more healthy and do things i love more because life is short
