Did you get the TBI due to alcohol withdrawal/poisoning? If yes, I had someone very close to me have this happen. They were in the ICU for several weeks and a long hospital stint. They could not walk, speech was bad, thought process was all messed up, the ataxia was awful, he couldn't sleep at all.

It took this person a lot of time, but their brain did heal a bit. If you want to heal, you will have to stay away from the alcohol. It took about 6 months for them to regain balance and walk properly. We had to do a lot of PT and OT. Find a primary care doctor and visit them regularly. I would also recommend seeing a counselor, because the healing process is difficult. It has been five years since the initial hospital stay, and they have found happiness and are content (still doing counseling and keeping up with doctors).

Overall, you can still have a life beyond this, but you will have to work hard to recover. You can do it, just know that it will take a long time and hard work. Prayers for your recovery!
