Really great, although I really cringed at some of the decisions Izumi made, in hindsight i have made those same decisions myself, so i guess i have nothing to say about that.
For those of you in a similar situation to Izumi, focus on something. Whether it be a hobby, an aspiration, something. Focus your life on that one thing, while it may not be that healthy to focus on one thing, it will at least help you in your path to resume normal life, for my friend, it was science and doing things for the good of humanity, for me, it was creativity and the drive to create something truly awesome, hopefully you can find something to help drive yourself out of the pit that is anxiety and depression.
