Hey Mom, I'm so sorry for what has happened. I don't get to spend near as much time on these boards as I would like to...
I haven't been able to read your entire thread so I apologize if you already answered the following question...
Are you in counseling at all? I remember how physically ill I was in the beginning. I couldn't eat for days, I couldn't sleep, etc. When I started seeing my therapist, she reminded me that this is all such an emotional strain that even going without eating or sleeping just adds to the stress. I immediately got on an anti-depressant and sleeping aid. Just getting some sleep helped me tremendously. With a good night sleep and a little boost from the ADs, I was able to combat the emotional stress that much better.
