Hi, Frank, welcome to the community. Sorry to hear you're having a tough time, but you came to a good place. I wonder if you've found our forum for Traumatic Brain Injury:
http://neurotalk.psychcentral.com/forum92.html There may be some folks there who have had similar experiences.
Someone else will be along who will be more helpful than I am, but just wanted to extend a welcome. We might be in different "staterooms", but we're all in the same boat here!
