As far as the fatique is concerned-I know what you are talking about. I used to be so tired that brushing my hair in the mornings redused me to tears. I just did not have the energy.
In my case it was adrenal burnout. You could ask you GP to test you for that. And according to the websites I read, if one of your glands start giving trouble, so does the rest. (thyriod, ovaries, adrenal ect)
The swelling in your face might be because of your ovaries. I saw a program once on women whose faces 'swelled' when they ovulated. Apparently it is natures' way to make a woman look younger and more attractive to men.
I basically just went on a fast for a couple of days (consult your doctor before you do this) and I've been on a rather strict raw diet for a couple of years now, and problem solved.

Good luck.
