To be blunt, your treatment by the doctors was not negligent. It may have been lacking a bit but that is par for the mTBI course. The negligence, in my mind is on your part. Drugs use, whether after a brain trauma or not is extremely negligent. You can not change your or the doctors past behaviors. You can only move forward. Clean up your life, get good brain nutrition, and work on each symptom individually.

If you brought this to an attorney, he would tell you than your drug use makes any claim worthless.

Tell us about your ongoing symptoms and hopefully, we can help you move forward. Take personal responsibility for your recovery and you will do much better.

My best to you.
