I don’t have any financial skills to offer, sadly. On the issue of other people being in worse situations, though, my thoughts are that ten years is a pretty appalling time to be waiting for a solution of some sorts.
The other thought is that there are of course many people in dire need, but this is the system our governments have given us and we all have to make it work to our advantage. I doubt very much that one patient not seeking treatment A will result in another patient receiving treatment B.
More likely, it will result in the powers-that-be saying that there’s no demand for Treatment A and that funding can be cut, which make the overall problem worse. This situation has occurred in my wider family, and I can assure you, no one wins.
