@shelly63 Are you going to a major medical center? I googled Budd-Chiari, I had never heard of it before, and I see that it is quite rare so you should be going to one, preferably one that does do liver transplants in case that turns out to be the best option. I think you need to do that and proceed from there.
I have no advice beyond that, but please be reassured knowing that there are options for you. I would presume that the first step would be seeing a hepatologist at a transplant center. That's where I started when I was diagnosed with cirrhosis.
I hope you will maintain contact, I will be interested in hearing how you make out.
