How are you feeling today? I hope its one of your better ones. I'm really glad to meet you, and I'm happy that you found NeruoTalk, too.
I don't know much about the type of condition you have, but I'm well aware of how frustrating a serious physical limitation can be. It injures your emotions and dulls your spirit as well as making you hurt. I hope that you have many more good days than bad. For me it varies all the time.
When I saw your post it made me grin a couple of times.

I'm divorcing after 23 years of marriage, and have three kids, except two of mine are girls. And being a life-long auto technician, the first thing that popped into my mind when you mentioned TBI was "throttle-body injection". I used to work on those a lot.
Anyway, I hope that you like it here and come back often. Good luck and best wishes to you, Sheila...
