I'm sorry that all this is hitting you at once. That sucks! I have been raising my daughter for 3 yrs without dad, but I can't imagine raising two kids alone ALL the way. I'm remarried and that's been a big relief. I don't have enough stamina to go it alone, I admire you!
I had a big flare up in my PN about a month ago - thought I was dying and went to the ER. Only "abnormal" was my temp slightly elevated. Turned out that I ended up with fullblown flu the next day. Spent the next 2 days with a high temp and so weak I could barely move. Things are just NOW stabilizing with my PN - (I finally figured out to start back on my vitamins) - so I think flu or cold can make symptoms much worse and probably deplete nutrients.
I don't know how you cope with the stress! There is this cool guided imagery CD I listen to called "A trip to the beach" that helps me forget about all my nursing school stress and lets me sleep.
So, most of this info was pretty random.......but I DO hope you feel better.
