I think you should be prepared that as you get better, you may be able to better analyze how bad off you are. That happened to me continually for many months and it really made me feel bad emotionally. I still have issues with how long this process of recovering from one concussion has taken me - I'm more than 20 months out from the injury I sustained.
Just try to focus on the good things in your life. I don't know what they are, but I'll give you a few:
-You have children you love.
-You're not worse than you are.
-You're not in a coma.
-Statistics are in your favor that you'll be doing MUCH better in just a few months or less.
I know it's a lot of change in a very short period of time and that's not ideal for any human being - even if it were change that were desired.
Be compassionate with yourself. You're recovering from a brain injury and that's a big deal. Give yourself some time to get better. Take it easy. Rest.
Trust me, I know how hard this process is. It's not easy. My prayers are with you.
