In my case I finally realized that my career was not just MY career, it was my escape from my bad marriage & when I no longer had my career, I was trapped financially in my bad marriage. That was why my depression got worse & not better but because I had been functional all my life, that was the behavior that was dominant .
My best help after finally leaving my marriage was my DBT therapy. It taught me to put words to my feelings. I remember one day just going in to see my private T & she asked me how I was feeling. All I could way was "UGH....JUST UGH". she brought out a 10 page list of emotion/feeling words. I took the list & made a 2 page list of my own with all the words that fit how I was feeling. Then I went back & elaborated with the reason why I was feeling the word. It was the exercise that opened up my mind & connected my words & feelings. Amazing experience that I continued to grow from.
