Great story. I was struck by a car and almost killed. Broken neck, broken leg, and major head injury. I thought I lost my career and ability to bike. Never give up. Never give in. Ever.
A book I drew inspiration from is Fearless.

Fearless is probably the best book I've ever read. Unbroken is also an excellent book, and the movie is being released in December I believe. If you like longer epic fantasy novels I suggest Game of Thrones. Cliche but fantastic books. Haven't read them all but I'm watching the show right now. But seriously Fearless should be required reading for every human being. Absolutely outstanding book. Highly recommend to anyone.
There was an actual SEAL and a Team Six operator that became a seal after being a meth addict:

Upvote for the one about Adam Brown.
It's called Fearless and it can be found here. His story is one that inspires me and pushes me everyday.

Hope you'll like it! What you've written reminds me of Seal Team Six Operator Adam Brown
