weight and measurements

so yesterday was my weigh in day..... i gained 3 lbs, all my measurements have stayed the same except my thighs that went down 1 inch(although since it was a different person they prob measured wrong)  my BMI is 45% AHHH shes like for your age it should be 22% dont worry hun it will take a while but you will get that number down.... im like yea i know ive lost and gained weight numerous times it doesnt bother me, yea id ike to be skinny but id also like it to happen on its own like it did before without me exercising lol. granted i didnt have healthy eating habbits either - was practically starving myself lol. and i dont want to go that route again....
