I was diagnosed with a lung disease which was quite aggressive and required a lung transplant I had many times when I died and was revived. I would feel a tingling in my head due to lack of oxygen and then wake up in Intensive care. In my mind I experienced pleasant thoughts, for five weeks the doctors hounded my wife to turn of the life support, while I was living in another dimension. When I came to, I was floating in and out and that world blended with the real world, it essentially became my reality. It was far from unpleasant, it was weird but not unpleasant. Treat your physical symptoms and get our affairs in order. You should not suffer regardless, when you see a child less than 5 years old getting chemo think of everything you have done and achieved that that child never got to do. I hope with all my heart you manage to pull through, my chances were 5%. But if you don't, please make sure you take whatever you need to not suffer. My mother decided to be a pariah and was anti-medication due to stigmas. Eventually I talked her into taking what was necessary, her journey was peaceful and most importantly painless. She was suffering the same disease as me (very similar) and slowly losing the ability to breathe, I can tell you I would rather just get hit by a car than go through that, but I did and was lucky enough to get a lung transplant. I am not sure if this will make sense to you, but I wish they pulled the plug because surviving in my case leaves me suffering every day with limitations and medications that are cytotoxic (cause cancer). My thoughts are with you, and I hope you get the best outcome for you.
