Medium is certainly not alone in lack of attention to user issues. Like you — there are parts I like and others that annoy me. Change is very challenging. The older one gets, the less one likes it.
Reiki? Good for you. I seem to be able to use it on animals and sometimes on people. Not on myself. I managed to almost get to Reiki Master.
In the area of vibrational medicine/energy healing, I have recently begun to study and use accu-pressure to try to deal with extreme pain from osteo arthritis. I am getting guidance from a friendly accupuncturist who works close by. It does appear to help — there is a LOT to learn. ;-)
Peace and hugs
