Hi there.
My Beloved Nan had kidney failure for 7-8 years... she battled it for many years, but unfortunately, her body became extremely weak and her health took a turn for the worse, she suffered from other health problems, too, and she was in hospital for about 6-7 months, then she passed away...

I wish you good luck on whatever the specialist says, and hope you will be okay. I really do wish you to be well and that whatever is going on can be fixed or handled with and you to live a long, healthy life...

My two cents worth.
(even though I'm in the UK!)
