Symptoms of Kidney Disease?

Lately, I've been having Shortness of breath, extreme fatigue, and mostly frightening, less Urination. I could drink several bottles of Water and urinate only about half of it. I'm gonna have my Mom(I'm only 15) schedule an appointment, and see what's wrong with me. This has been happening for the last 2 days now. Does anyone have a clue what could it be? I'm hopping it's not some Kidney disease.
