Gaining the clarity to "do what feels right" is a magical thing indeed. It becomes an indestructible road map to a better life, when you can really and truly examine what you're feeling.
The gym saved my life too (laughing). I found that after making my heart pound and my muscles work for a while, things still hurt but not nearly as sharply....more like a dull ache than a sharp poke. And then eventually the dull ache went away too, and I could just wish "him" a happy life while I went about mine.
Hugs and hope and strength for you!
