Of course, you are feeling frustrated and discouraged.
I felt the same way when I was listed for a liver transplant in 2008 and had to be 'inactivated' from the transplant list for a deceased donor because of possible cancer in my bile ducts. However, after being tested and cleared of any cancer, I was 're-activated' on the list. It was not an easy journey emotionally and physically, however I am here now and doing well as I approach my 17th year anniversary.
Alicia, this is a one-day-at-a-time process, so try to focus on the positive while holding on to hope. The transplant team will do all that they can to get your husband ready for the surgery. As for yourself, please take care of yourself so that you will be healthy and ready to jump into action as a donor.

I am not familiar with plueral effusion that your husband is experiencing, but want to ask if there have been any sign of improvement?
