Journaling is an excellent tool for tracking how we are feeling. I have journaled for over 20 years ! Your T may or may not want to read it - but at least you can tell him/her about the time frames. I have ALWAYS made myself put at least ONE positive thing in every day, even if it is just that I got the dishes done before I left for work, or that I watched a hummingbird on my feeder. Perhaps you can start adding at least one good feeling, thought, action, etc as you journal. Sometimes it helps to stop the more depressive thinking process......and rereading it might show you have progressed more than you are able to recall. Good luck !
