Hello DrewSpouse and Welcome to Neurotalk Support Groups,
I am so sorry to hear about your husband's accident. That is a lot of stress and worry. You will find this a supportive place with many friendly people.
Here is the page for
Traumatic Brain Injury and Post Concussion Syndrome
and
Caregiver's Support
There is a handy Search feature and an FAQ for answers to common forum usage questions at the top of the main forum page.
Have you discussed the situation with your husband's doctor? If there hasn't been a psychology consult at your husband's rehab facility, ask for one. You may also want to get the social worker on board.
I hope things get better for you and your family soon,
