For me it depends upon the topic. Anything with a CBT therapy component tends to go quickly. Panic attacks, facing down anxiety/phobias, countering the agoraphobia - those were all relatively quick adjustments with big payoffs.

CSA/trauma and interpersonal relationship stuff? Much slower and harder to track. Overall forward movement progression, but not necessarily in a straight trajectory. The topics tend to come up, get replaced by something else, later come up again in a different way, regress, surface another time to address a different component. More cycles through the same topics.

The behavioral stuff comes back up every now and again, but it is always weaker and less of an issue each time it makes an appearance. My skills are now stronger than my anxiety. CBT has saved my life.
