Too bad

I hope I dont' get it. I got one of those things when my dad was diagnosed a few years ago, just to make sure. I had some of the symptoms, like excessive thirst(I drink a ton of pop, tea and some coffee though it's probably cuz I like caffeine and it is a diuretic so I want to drink more). I tested myself for a couple weeks and it looked ok, but I went to a doctor and talked to him about it. He said I was probably ok because of the meter readings. Maybe I should have taken the blood test though. I try to exercise more and eat better since then.
