Really, weight does not matter based on how old you are. Your height has a lot to do with it though, and of course how active you are. A BMI (body mass index) calculator is a good way to determine if you are at a healthy weight or not.
According to the BMI & based on your height here are the healthy and unhealthy weights:
Underweight- less than 108 lbs.
Normal- 108 lbs to 145 lbs
Overweight- 146 lbs to 174 lbs
Obesity- 175 lbs and above

no i think that is perfect for a 5 foot 2 or 3 inch girl!!! i was 65 pounds in my pre-teens, so fear not :)
It might be too thin, but every person is different. I'd say 120 would be better, assuming you're active.
