LGBT: Does anyone know what might be wrong with me?

This is more of a health question but that section seems a bit dead at the moment. Anyway, for the past few days I have been really thirsty, it's like every 5 seconds I HAVE to drink something. Then at random times of the day I get like this ticklish feeling in the tips of my fingers and toes. And finally one last thing. I'm hungry....like all the time. No matter how much I eat I still feel hungry and I won't gain weight. What the hell is going on?
