Hello ZooCrewGal,
Welcome to the NeuroTalk Support Groups.
I'm sorry to hear about your 2nd head injury.
Check out the
Traumatic Brain Injury & Post Concussion Syndrome Forum
There are quite a number of people dealing with a second impact.
There are also lots of useful resources in the "Sticky" threads at the top of that forum. Just take it easy and don't read it all at once.

Rest up!
Take care.
