Hi and welcome. Sorry to hear about the accident and it's certainly a justifiable anger since it wasn't your fault. That said, being angry won't change anything, and a negative emotional state may be detrimental to your emotional recovery.

I too had a near fatal accident, and I had to go through a lot of changes, physically, cognitively, emotionally. I also have a professional career that I was away from for six months.

I tried to always maintain my sense of hope and gratitude. I was grateful to still be alive, and for the surgeons, doctors, nurses and therapists who were there to enable my recovery. I remain grateful to family and friends who helped me recover. So I guess my suggestion for your “what can I do besides rest” question is to realize it could have been worse, realize you are early in your recovery, and people do recover. My neurosurgeon told me a few weeks after I was released from the hospital “I didn’t tell your family this the night of the accident, but I didn’t think you were going to make it”. Yet here I am, back to work, and looking forward to the rest of my life. Miracles in recovery indeed happen. I wish the very best to you as you continue your recovery journey.
