wow omg, your guardian angels are certainly with you!
So glad you are alive!!
Take it easy & hope you heal up alright.
From my experience in having a head on collision 14 yrs ago (not my fault) - the third & fourth days were the worst for pain & more soft tissue injuries.
Please rest a lot, get yourself a lawyer when you can & make sure to write a journal & document your pain, feelings, inconveniences & injuries. Even get help & have someone else write for you if you need. It might seem like a chore, but in the end that will help you a lot (my advice from experience).
Thoughts & prayers are with you for a speedy recovery & overall wellness!
