Debilitated,
I too am concerned for you. You seem to want to be self treating. I think at this point you need to trust your doctors and follow their orders. Right now its obvious to even the untrained eye that you are very ill. I highly doubt they will even think about surgery for you at this point. You can barely walk to the BR without getting winded and have your heart racing. Just let your doctors treat you, and let "them" make these decisions for you. I wish you well.
