@Roberta,
Thank you Roberta and others who read, yet say nothing.
My dad taught us not to give up and sometimes that is exactly what I want to do. I want to run away and not come back ever. Then reality sets in and I know that is not the answer. I can't or will not run away from reality or any problem that I feel is worth fighting for.
My sister is worth fighting for, even if I don't know what to fight against. That is what angers me. The doctors, who I highly respect, can't find the source and the technology of the machines can't either. It is so frustrating because I do my best under pressure when there is a solution. I am not finding a solution at this time.
