I think you could also have misinterpreted your T's response. She could have just been warning you, so you do the making-sure thinking and checking your heart (as you have done beautifully) to make sure you are not fooling yourself and being misled by the depression when doing something else would have been helpful.

I once interpreted what my T said to me as insulting :-) when she said the good thing wouldn't happen, "if you do what you usually do" but she was just saying, "Watch out! Rocks ahead! Heads up with steering the boat!"
