Thank you all so much for your well-wishes, I truly do appreciate it.

NWIFlyer, I'm really pleased to hear that! I've heard quite a few personal anecdotes about transplantation at this point and nearly every single one of them have been positive, which is hugely encouraging, especially as I'll most likely have to go through at least two if I manage to sustain a somewhat normal lifespan out of this defective husk. Adding that one to the list!

As suggested, I will indeed get in touch with BA - will update this thread with the outcome in case it might help someone in a similar situation in the future.
