So i have been feeling....off, for about 9 days now.
I am:
*constantly tired
*really thirsty
*urinating alot from the thirst
*i get shaky at random times
*verrrry moody. i usually don't argue with my dad (i must admit, he is intimidating and scares me, so i usually stay quiet) but lately i have been. its freaking me out
*i get weak sometimes,
*frequent headaches

*weight loss, 20 pounds in a month and a half
*and everytime i stand up, whether i have eaten or not, i get extremely dizzy. It gets so bad that it begins to hurt my eyes, and a couple times i have fallen down because i couldn't see/it hurt too bad.

What is this? I am pretty sure NO ONE that is relatively close to me in my family has diabetes! Maybe a distant cousin or uncle, but thats about it. My mother has Chrons' Disease, but i don't have that because the doctors have already checked me. Twice. What is going on here? Can someone please help me? Could this still be diabetes? How much longer could i go with undiagnosed diabetes before something bad happened?
