Me & My Shadow

First there was the long-term lung infection (trachio-something-or-other bronchitis), then right after that ended I got a bladder in fection, ad only after a few days of that seeming to be gone, it came back again.  I'm just finishing off the medication for the second bout of bladder problems, and after a few days of huriness in the left side of my jaw, now I'm getting an abcess/infection there, and feel like a sinus infection is on the way.   Literally these have all been pretty much back to back, within days of one another.  I don't wanna go on yet ANOTHER antibiotic, just after this whole string of bodily weirdness, ya know?  So, what the hell is going on w/me??  I've heard diabetes can cause this sort of thing, but know that stress can jack your healt up, too.  Any helpful hints or suggestions, anyone?
