Is my daughter diabetic with type 2?

She is 12 years old. She usually exercises 30 minutes a day, but her PE course hasn’t started. Her diet is unhealthy, and she eats healthy food once a day as well as milk. She eats a lot when she feels like it, but sometimes she eats a little and gets full easily. People say she has gotten thiner, and she said sometimes maybe once a day or less she feels a tingle in her fingers for 5 seconds without any pain. She goes to the toilet 3 times a day, has 3–5 glasses of water at the most. No one in our family is diabetic, ever. She Is not white, from Asia but born in America. We took a blood test around spring 2010 and they said she was not diabetic but has high cholesterol, and she feels no pain whatsoever. When she gets only 5–6 hours of sleep, while she is watching tv after a long cold day from school she drifts of for half an hour which happened twice. We haven’t weighed her yet, she hasn’t lost weight she is still the Same. She is growing tall, and do you think she has type 2 diabetes?
