Help for my sweet son Doug

This is one of the hardest things a mother could ever have to do!!! My son Doug  was airflighted to University or Cincinnati trama center on Friday Nov. 23rd the day after Thanksgiving... We did not think he was going to pull through the night, due to the fact that he had went for a while (UNKNOWN HOW LONG) without oxygen to his brain. In the past week it has been rough for all of us but more so for my son. He has been asleep every since they brought him in. The did find brain damage on his MRI but to what extent.. we still don't know.. They did insert a trach and a feeding tube and he is now in stable condition but still not waking up.  Unfortunately he has no medical insurance and the surgeon today said this is going to be long term. I can't even imagine what his bills are already up to but this will be a tremendous cost for him He is an amazing father to his little 5 year old son Bryson and Bryson adores Dougie as well!! They have a strong bond that can NOT be broken but this is really going to be hard on both of them...Please pray for our family as this is devastating to all of us!! Please God bring back my Boy!! We need him.
