Welcome Marg.
I'm sorry you are having a rough time. This is a wonderful, supportive community.
One of the greatest things I have been learning from the people here is to try to stop asking "how long until I am back to normal?" The brain is still too much of a mystery to scientists at this point. (glad something is, but too bad it's my brain.) Don't get me wrong, sometimes I get very down about it. But I am learning gradually to just be where I am and not constantly try to count the days. I have also finally started explaining this to friends and extended family who ask. A lot will happen over time and rest. That is so vague that you probably want to strangle anyone who says it to you again.
I had an epiphany in the first month after hitting my head and experiencing this incredible loss of power in my life. Then I realized that the idea that I had control over things was an illusion anyway. Since then, I try more to let go. (try is the operative word.)
Hang in there and stay positive! You are among friends.
Julie
