Maybe your T thinks that you waste too much time and energy being concerned for your health and are foregoing other good things in life.
I agree with Ben. God can and does perform miracles, but He'd rather us "go through" a problem so that we gain endurace and learn from our experiences.
I feel that you need to communicate with your T and clear things up for yourself. I seriously doubt she was "gloating." Most therapists take that job because of an inherent need to help others.
I may be wrong, but maybe she felt you needed some kind of a challenge or a shock to move you out of a place where you are stuck. This is what Ben refers to as "an ordinary miracle."
