Diabetes Question?

[mradrz4evr]

I am fourteen years old and have some concern that I might have diabetes.
It exists on both sides of my family, though neither of my fortysomething parents have it. But lately I get really lightheaded when I stand up, as well as being drowsy and oftentimes very thirsty. One day when these symptoms were exceptionally bad I went on webmd and diabetes came up. I am not overweight, but it does have a history with my family, so I wasn't sure what to think. Anemia also came up, but I take iron supplements daily, so I didn't assume that was the case. I don't know whether to pursue this, see a doctor, or what else. Any advice or personal experiences help. Thanks.
