Emyjay, I want to say so much, but am a bit reluctant, so I'll leave it at "the outcome is up to you."
Might I suggest a couple of books, "Healing From the Inside Out" and "Hormones, Health, and Happiness." I have many more to recommend, but those two are a good start.

Weirdest thing just happened. The system logged me off and I couldn't get back in. I was fearful of offending Emyjay, but I think I should have been fearful of offending the board too... anyway... to finish my thoughts:

I researched vitamins and minerals for my mom (sorry about referring to her again, but I think there's valuable info involved). I wanted something that covered everything, especially her dramatic mood swings. The owner of my herb/health store recommended a pre-natal duo - a multinutrient (vitamins and minerals) combo pack with DHA. Our mom has been on it for going on 2 weeks, and believe it or not she has not only quit her continuous crying, she is MAKING JOKES about ANYTHING and EVERYTHING. She's laughing and smiling so much it's almost as hard as her crying... I definitely can't keep up with her (but I certainly prefer this than the morbid thinking she had before). How long will this last? Who knows. But, at least we know she was vitamin/mineral deficient in some ways.
