Am i Fat :( .........?

You can try doing things in your life, like walking home after school, going on a shopping spree with your friends, go for a jog at the park, maybe go swimming, whatever you want. You could take your dog for even longer walks, then you could both get fit! Yeah I'm 13 and your weight as well... so thats what I've been doin, and I've lost a few kilos so yeah try that maybe it will work for you too. Hope this helps =)
