I can relate to your issue since I once diagnosed with some serious health condition and ignored until I cant handle. Ive been on a point that I already accepted my fate and just leave the decision to God if he will give me more time or not. I know this sound like a religious preach but praying is always working in times you feel that you cant make it. Its good to have faith to hold on rather than become on panic or nervous state on whats to come.
I work with you a lot of times in the past and I witness how you progress you career here in the forum. You persevere to achieve all the credentials that you have right now and Im sure you can do this kind of progress on your health battle. Even though we are not family but I will include you on my prayer for your speedy recovery. Godbless men!
