Hi there. A couple of questions/comments:
When was your injury and start of these latest symptoms? Recovery takes time.
You have a great resource with your AA meetings, rather then "trying so hard not to feel" that's a great place to acknowledge your feelings. When we realize what those feelings are we can take steps to resolve them. It's not unlike the first 3 steps in AA. If you have an AA sponsor that person could be a great sounding board for the stuff related to your TBI/PTSD.
When I was a couple months home from the hospital my family got me my "service dog" an adorable pug names Keona (Hawaiian for "God's gracious gift"). She is indeed, a day doesn't go by without a few hugs and kisses from her to make me feel better.
Hang in there. Best to you as you continue on this recovery journey.
