Weight problem

So I recently turned 15 and I’ve had hypothyroidism for three years. Even with my eating healthy I mean I might eat a piece of chocolate on occasion who can help it, but I work out every day. I never take a day off I do cardio mostly dance and strengthening exercises. No matter I can’t lose any weight in fact I’ve gained weight. It’s devastating I’m doing everything right and it’s not helping I’m obese I now weight 193.5 lbs and am 5’5” help...

This is my body
