How many sessions will I need?

This really varies by the individual and the issue. Some people have issues that are more tricky and developed over time and these issues might take more time to work on. That said, if you are motivated, work on coping skills outside of session, and are focused on your goals you may have a very short time in therapy. Normally the shortest time tends to be around 2-6 months of weekly therapy. It really depends on the issue and the individual. If cost, time commitment, or just being uncertain is an issue, you should try Single Session Therapy.
