TBIs take a long time to recover. My moderate TBI was 30 years ago, and it took about 2 years to get to 70% and 8-10 years for "full" recovery. It was several years to tamp down my mood swings (basal frontal lobe) from injury and life; I don't know if therapy is an option for tools to herd emotions. I keep lists because I don't remember numbers and peoples' names (left temporal lobe, aphasia). It helped me that I gave myself permission to fail (I was writing my PhD disseration at the time). Recovery takes a lot of energy, but rewiring is helped by the usual: get enough sleep, de stress, avoid mean people (TBIs bring out the worst in others), learn new things, do word/number games, spend time with yourself and friends, and remember that you are still you.
