Suggest Treatment For Mood Swings, Impaired Thinking And Sleep Issues Post Head Injury

I fell & hit my head 8 years ago. I experienced mood wings, sleep issues, poor decision making. I ve spent most of this time in therapy and on a wide range of medications. I quit my job with benefits ie disability & I have struggled financially & emotionally ever since. I just recently quit seeing my specialist & taking all the medications I was prescribed because I could no longer afford them. I m finally beginning to feel like myself again but with slower thought process. Its like I ve just woke up. I ve gone through countless jobs and I m ruined financially. I ve blown through my retirement & kids college fund. I ve lost property that I used as collateral to take out loans. I m losing my home to foreclosure. I have a job making $11 an hour which is more than I ve made since I quit my position as an insurance agent making over 6 figures in 2011. I ve filed Chapt 13 and I m struggling to keep up with those payments. Any advise of how to start over?
