Hey so I’m a little nervous cuz I don’t usually do this stuff but I’m worried about my weight all the time cuz this one guy called fat... I can’t stop thinking about it and I’m worried about what I should do. I think I’m about 5’3 and I weigh 100 lbs (45.385 kilograms)

I’m not sure if that’s overweight or under but I’m just stressed about it all the time now.... I started working out about 2 days ago but it didn’t change anything.I’m 13......
