Ugh...

I left work early today because I was not feeling well. I don't know what it is, but for the last few weeks I have been ill. I've been sick to my stomach, have had trouble eating and sleeping, and have chewed my fingernails to the nubs. A lot of that is from stress and my nerves. I know that, but why after two almost perfect days, are my nerves getting to me?? I don't understand this at all, but I know if it does not stop soon, I will go crazy!!
