Hi Steve,
welcome to the group, I too have been in the RVI-fantastic regional centre.I'm post 8 months now, and managing to work full time again, and just got my license back last week from DVLA.
what you are going through is perfectly normal, take each day as it comes, plenty of rest , listen to your body, let the family help you.I love quietness hate noise now.
There is a local monthly support group at the RVI which is great help for you and your wife, your not alone.
Take care, let's hope that the weather improves, and you can relax in the garden, take your daughter to the park when your feeling stronger, as your going to feel weak for a while.
Dont overdo it, tired have a sleep xx
