God has not forgotten you, please know He walks with you in this very trying part of your life. I am a nurse who has had the honor of taking care of a man who suffered a brain injury as well because of lack of oxygen. Doctors told the family nothing else can be done and call hospice after this happened. 2 years later he lives in his own home with wife, he has round the clock CNA care and myself to do meds ect. He will never be 100% but he is a long way removed from the state he was in. Please have faith in our God, he will bring you thru this. My patients wife and family are very devout Christians and I honestly believe it is the only way they have been able to got thru this. God bless you.
