Just read this and thought of you because I am always saying when the pain outweighs the fear, you will do something different. I am not saying you should because I see some positives happening. But I know that you question when you will know if you should change course.
There comes a time when the pain of continuing exceeds the pain of stopping. At that moment, a threshold is crossed. What seemed unthinkable becomes thinkable. ...Slowly the realization emerges that the choice to continue to keep doing what you have been doing is the choice to live in discomfort, and the choice to stop what you are doing is the choice to breathe deeply and freely again. Once the realization has emerged, you can either honor it or ignore it, but, you cannot forget it. What has become known, cannot be unknown again.
