Thanks everyone from post #23 down. I'm still not feeling so well and I think I'm going back to the doc tomorrow. Trying to avoid mgh's situation if I can.
@Starise: I'm not a big fan of sugary things, but that's interesting to know.
I think this was brought on by stress, and just not taking care of myself in general the last few weeks. The pressure of not having a job, trying to sell and buy a house in an 8 day window, and move 13 years worth of crap in that time was just too much. Then I found out today that our house isn't going to sell up in Iowa. The people buying it supposedly 'accidentally' gave the bank some 'wrong' information, and now they can't qualify for the loan they were already pre-approved for. It's times like these that I just want to wander off in to the desert and never be seen again.
Aw well. This too shall pass ...
