Life is an experiment, what fun is it otherwise? I say try anything and everything. Give therapy your best shot, be open about your struggles, do your own research, and have COURAGE to face new situations. There are some really good therapist, there are not so good ones, but in the end it comes down to you. If you're willing to put yourself into difficult speaking situations, practice, and overcome your fear, you will likely see progress. If you rely completely on your therapist, but don't take risks, you'll likely not progress.
