Maybe she has chronic fatigue syndrom, or fibromyalgia. Or she could just be depressed because that will make you feel exhausted and overwhelmed. I think the best thing you could do for her is talk her back into going to counseling. OR even seeing another doctor for a second opinion. She definately has something going on with her health.
I hope that this helped some.
