A month and a week isn't very long after TBI for recovery.

Sounds like you need to take some serious time off. The brain changes for sure after concussion, and it will continue to change. So, the short answer is, Yes, you can make a full recovery. A lot of people do. It can just take a lot longer than you expect, and you may find aspects of your life changing that you would prefer didn't.

TBI/concussion is like having a tornado go through your town -- some things it trashes, some things it leaves intact, and it's not always clear why. It's also not always clear how the "infrastructure" of your brain is/was affected. Some changes take a while to show up, while others show up right away.

My recommendation is that you treat your head injury like you would treat a tornado that tears through a town with a limited budget -- it takes time to assess how everything has been affected, and it takes time to rebuild. One thing you can do that can help is practice types of breathing that calm down the nervous system and get your system out of fight-flight mode. Slow, measured breathing and relaxation helps take the edge off your high-alert state, which makes it easier for your brain to recover.

That intense high-alert state and the fight-flight priming floods your system with biochemicals that actually hinder healing and learning and higher functioning -- all of which your brain needs. If you breathe slowly in for a count of five, then breathe out slowly for a count of five, that can help retrain your system to calm down. And that may help your nightmares as well.

The worst thing about head injuries is the uncertainty, and that can stress you out and keep you on edge. Rest assured that a lot of us have been through similar, and there are a lot of us who are now back in the game. It's not easy, and it can take time, but it's definitely possible.
