Welcome to NT.
While all brain injuries are different, many of us recover fully or substantially. While it may now seem like a long time since your injury, as brain injuries go yours is fairly recent. I saw significant progress cognitively and emotionally in the 3 to 6 month window after my accident, which I largely credit to physical, occupational and speech therapy. I was able to return to work six months after my injury.
You have found a good place for support, continue to ask questions and please share your successes and frustrations on your recovery journey.
Best to you.
