My brother had this condition, had the blue tinged skin and fingernail beds. He died 7 years ago from complications of his morphine addiction the doctors got him hooked on.
She is a lovely person and I wish you both the best. PS, you may want to speak with someone who actually lives in a country with socialized medicine. I have a lot of friends in Europe and Canada (I'm a recording artist and work with a lot of people in other countries). People with life threatening conditions get the care they need.
That sounds like something I would definitely look into! I am so sorry to hear about your brother.
I can only imagine how difficult it must have been. Hopefully you are doing well, healing, and prospering.
hugs
Namaste
