Wepow...one of my sisters is going through exactly what you posted about...her problem turned out to be peri - menopause/menopause and anemia.

I dont know how old you are but these stage of life can hit women as early as the middle 30's and as late as the 40's and 50's.

just an idea you may want to consider.

for my sister the solution was mega doses of vitamins and hormone replacement therapy other wise known as the birth control pill tailored to fit her biological /chemical needs.
