If your therapist is teaching deep breaths and slow talking and ways to control your stutter in order to be more fluent, that's a pretty old fashioned way of understanding stuttering and doing therapy (fluency shaping). For the record, it doesn't work for the vast majority of people who stutter and personally I think it's harmful and a waste of time. You take back control of your life by switching from trying to control and suppress your stutter to not only acknowledge but also accept that it is part of who you are, and also by not fighting it. By letting yourself stutter. This is obviously much harder than it sounds and even harder to do on your own. But stuttering in itself isn't a problem and won't control your life. Doing all the things you feel to try to avoid stuttering and avoiding all the negative feelings you feel when you're about to stutter is what causes the problems. You can slowly work on reducing shame around stuttering my very slowly and in tiny baby steps, let yourself stutter just a little, feeling negative feelings if they come up, and over time you will learn stuttering is not as bad as you made it to be and they will reduce. Again, doing this is not easy, especially trying to do it on your own. If you like your therapist but don't like fluency shaping, you can ask her to look up avoidance reduction therapy for stuttering
