If your old therapist isn't returning your calls find a new one. Lots of therapists don't know jack about stuttering and often do more harm than good (FYI I stutter and am a SLP). Also- I would suggest attending a local national stuttering association chapter. There are international and online ones too. One thing that helped me immensely was just realizing I'm not alone in these struggles (which you aren't either!). www.westutter.org.
