i am a mac computer user and i use optimism software to help as part of managing the triggers of my depression. I want to quickly note for other macusers that optimism software is being promoted at macupdate right now.
i think it is ground breaking that mental health related software for clients has become this mainstream so suddenly.
the software allows a week for a free trial in the shareware tradition. those who opt-in with macupdate can purchase in the next day or so for half off as part of the promotion.
i won't spam you with urls. i am sure that if this interests you that you can find macupdate anyway.
if you want to try to manage your depression this winter maybe you might ask your T. if software like this can help you both get a handle on your problem.
in my case finding the right mixture of meds was critical. but using this software did stop things from getting out of hand in the bad times because i was cognitive.
have a happy new year!
