You're stuck in a new world where nothing seems real to you. Forgetting you're whole life from before doesn't make things better not to mention the head injury you have.

Trying to live through all of this won't be easy, nor will understanding half of it. Maybe things will be better than the life you lived that you can't remember. Just don't think too hard, you may regret it.

Life will be different, life will return, life will go on but how is the question.
