you have gotten some great advice and I am going to try to outline it for you!!
1. Give yourself a break. As women, we don't know how to take care of ourselves and I think you are in that mode right now. No one can take care of you but YOU!
2. Get a checkup -- you might need Iron or Vitamin D or B12 or something.
3. Take a step backwards. Start making a charity baby quilt or lap quilt (Project Linus comes to mind) with a four-patch or a nine patch. Making something for someone you don't know is good for them and good for you!! I have done this a lot!!
Hang in there and take your vitamins!!
