What is the average weight for a 5' 7'' 12-year-old?

I'm 5'5" and I'm 12. I'm 85% above the average 12-year-old girl's height. I'm 105 pounds but I have to be slim since I'm a model. My doctor says I'm healthy. 5'7" you should be getting into the adult sizes so it should be more average to an adult weight say 120 pounds-145 pounds max, if your shoe-size is 6,7 your staying that size if it's more 8,9,10,11... you should grow an inch or two.
