I have known several people in similar situations (from different causes) who made the same decision you have made. After a while they got tired of it all, and although it may have LOOKED like they gave up the fight, what they were actually doing was accepting what was, and making peace with it.
When I pray, I never ask Him for specific things, I only ask that His will be done, that I can accept His will joyfully, and if by some chance He can use me to accomplish His will, that He go right ahead and make me a tool in His hands. He knows you have great faith in Him, and whatever His will is, you accept it. There is no higher calling than that.
