PCSupportGuy,
Welcome to NeuroTalk.
I can not cite any studies but it is well known that stress slows recovery from a concussion. I wish I could offer suggestions but your situation is a big part of your struggles in my opinion. Do you have any family that can help out ?
Many of us do much better with a good vitamin and supplements regimen like that posted in the stickies above.
btw, If you wife is a similar age as you, she may need some serious hormonal help. My wife had me on egg shells at about 50 years old. She found a good women's hormone specialist and it changed both our lives. Most gyno's just throw a shotgun load of hormones at their patients. Here is a link to a referral source for hormone help.

My best to you.
