Like I said before @cryptopie. You are one of the strongest people I have met. Look at you, still fighting strong after 17 years of this terrible sickness and like you said, only God knows why this is happening to you and He controls it all and it is never over, until God says it is over and God performs miracles all the time, and I will always pray for yours, dear friend.
What a wonderful brother you have to be able to help you with your medications etc. God Bless him and you and your whole family.
