I lean on my therapist hard when I'm having a hard time. When I am hopeless, that's when I "enjoy" going to therapy the most and listen the best because I always have that tiny germ of hope my therapist will say or even imply something hopeful I can use to keep going.
I am a very literal or "concrete" individual and my logic is very good so when my therapist says "I understand" I take that at face value and add that one very important :-) person to my "side."
In the top 10 experiences I had while in therapy for anxiety and depression (1970-2005), one of the ones near the top would be when I figured out for myself that my feeling of being Chicken Little ("Help! Help! The sky is falling! I have to go tell the king!"
http://eleaston.com/chicken.html) did not jive with what I saw in my therapist (calm, quiet, comfortable, took time formatting her response, worked hard not to upset or "argue" with what I said; did not feed into my "will struggle" problems (e.g., I was always "right" and "believed")). I put those two things together and came up with the understannding that either the sky was not falling or my therapist was crazy :-) That understanding was immensely helpful to me afterwards as I could refer back to it and use it to help me in difficult situations. When I was confused, angry, depressed, frightened, etc. I could think how my therapist would respond and "adopt" that response for myself through her. I used her as a "proxy"
until my feelings and understandings caught up.
Depression can be overcome. Your therapist gave you a concrete example of someone she has helped. If your therapist helped that person do it, there is no reason she cannot help you do it. Therefore,
your depression can be overcome. Believing that, even if only by proxy, it is possible to be "hopeful" and/or to work toward that end.
Any work toward that end is helpful work toward your goal. So, anything you do that is "anti" acting depressed, is work toward your goal. Take a shower, eat something healthy, read a little, do something positive
as well as sleep too much :-) AND see it as positive and helping you combat therapy.
