Seriously, hypnosis? I think at thins point it sounds like you yourself may need some sort of help dealing with the desperation you are feeling. If you are feeling that you are 'desperate' and willing to try anything, because nothing is working... I suspect you are not coping well, and may end up negatively effecting your child by making them feel anxious.
Really there is a good long term prognosis for this disease. The scientific community is honing in on the causes, and several drugs are being trialed which have already shown very positive results with patients. There is no 'cure' outside of a therapy that will address the underlying problems with the immune system. Until that treatment is available, what you are doing now is to minimize the effects of the illness, and improving overall health without aggravating the illness.
In general, rest while experiencing malaise and fatigue, careful exercise when able, good diet, take supplements if you want,, meditation can help... but understand, that these are techniques to improve the overall health and condition of a person, not to 'cure' the illness.
I have had many times where I have not felt able to get out of bed, but currently I'm training for a half-marathon, am working as a computer programmer, have a wife, friends... but still every now and then I can't get out of bed. I'm one of the lucky ones. It's not easy, but it's possible. Not if you get overwhelmed with feelings of hopelessness. There WILL be a cure, but hypnosis is NOT IT.
