yes, it is important to understand that this is usually a gradual process, taking years to show substantial progress. i have seen it with TBI and with my own recovery, which took 7 yrs of daily therapy to "recover" from bipolar and that host of associates, Anxiety, OCD, Phobias, Panic, etc. i still am struggling with memory repair; and C-PTSD, because life for a person who is poor, alone, and impaired is not so very safe.
still, i had nothing more worthwhile to do, and the results are most welcome. i used an auditory therapy called Holosync (you can read about it and order the therapeutic format at

i also found that meditation enhanced my recovery, by strengthening my focus and lessening my reactivity.
best wishes for all who are struggling to recover~
