okay so like this started like about two weeks ago. i was tired and thirsty all the time, and urinating frequently. for a few days i felt okay kinda. but i just got this cold, and the symptoms are back worse than before. and i don't know if this means anything, but in the past few months i've been sick 3 or 4 times, and i hardly ever get sick...i mean, i hadn't had the flu since i was 8. what do you think is wrong with me?
