Hey! I found this documentary which.. I'm not sure how many people will be able to access.. but if you can, if you can, it's probably worth watching. (And it's not too long!)
It's about a 20 year old man who fell off of a wall while clubbing and landed on his head, he was in a coma for 5 weeks. I actually found it hard to watch.. not just because I struggle to watch tv anyway, but because it was so moving and too close to home. I'd mostly recommend getting people who don't fully understand your TBI/PCS to watch it. Maybe then, they'd see how you're affected.. and doctors also talk on it.. So they'd get some informative knowledge from people who actually understand.
People in the UK should certainly be able to view it, however, I'm not sure about those of us who live in America.. Apologises if you can't..
All The Best
