Your post resonates big time! I am 26 years out and you took me back to earlier days. A couple of things that helped me in the earlier days - hearing a psychologist tell me "do not let the transplant define you, do not let it change the person you were before, prior to liver disease".
Hard to do because liver disease is slow and it takes years to get sick enough to be eligible for a transplant. We lose ourselves over the years. It took a couple of years but I did go back to riding horses and having a good life.
The other help for me were postings form a heart transplant recipient who ended up aggregating his writings into an unpretentious but wonderful online free book. Here is the link:

You might pick and choose what to read, which article description speaks to you. Something quite touching about this man/author is that he met the mother of the young man who was the donor and they ended up marrying. Isn't that touching?

What I learned from that is that we have to get out of our own way, out of our heads and overthinking it and start participating in other lives - family, animals or otherwise - because there is a whole world out there , outside of our liver disease and transplant - waiting for us to participate and contribute. The novelty and the extra attention wear out and the world does not wait for us. Jump on the wagon or be left behind.
Please celebrate your upcoming one year anniversary, say a prayer for yourself, your donor and family and please tackle those challenges. Yes, there are a few but.....you can do this! Please, keep your wonderful sense of humor along the journey.....it helps!
