(((AngelEyesMom))) I'm so very sorry for your loss and complications from the accident. I wonder, did they find the other person at fault?
Have you seen a neurologist? I strongly urge you to if you haven't.
My cousin was in a terrible car accident a year ago March and was in the hospital for 2 months. Her many injuries included head trauma, and she has the same difficulties as you. One of the strange reactions she has is talking extremely fast and constantly. Her neurologist said that wasn't uncommon for head trauma and should go away eventually. She has terrible pain from the trauma to her spine. Collapsed lungs, 6 broken ribs, ruptured liver. It was all so awful, and I can only imagine how frightening this was for you.
I hope you find the support here that you're looking for. It's a great bunch of people here.
Again, my deepest sympathies for your losses.
