Hello, texgirl.
It sound like an interesting story you have there. I believe that the energy in hands can be used for healing. At least, I've learned several energy healing techniques and all involve energy emanating from the palms of the hands.
Also, from what I've learned, large auras are a sign of a large energy capacity in you. My healing teacher told me that large aura (or biofield, like she called it) is almost a necessity in order to heal with energy.
You can try to develop your energy feeling, see the following exercises I posted on my site:

I would like to know how you feel with these exercises and if they help you.
Thanks.
