I can totally relate with the same story – moderate/severe stutter when younger that got better through therapy in late teens so that by my early 20s, it was still somewhat noticeable, but not terribly limiting. All except for the phone - oh man. After graduating university, I articled with a public accounting firm and had mini panic attacks every time I had to call a client for whatever reason. I would avoid/procrastinate so bad that it led to some awkward situations and unnecessary time pressures to complete files. Plus, the anxiety would just build and build. What helped me: 1) “Eat the frog” – I would purposely make the call sooner than I wanted to avoid procrastinating and the anxiety build-up. 2) Exposure helped and even visualization – for a time, I mentally pictured every good/decent call as a red brick and then I would place this imagery brick with mortar on top of other bricks to build up a wall (I’m not really sure why a wall – a barrier with my stutter on the other side perhaps?). 3) Time/Self Confidence – It’s not really active advice, but now in my mid-thirties, I have no anxiety about making calls now (with the exception of when I have to make a phone call in French to Revenu Quebec – then I still get a little worried and the stutter is noticeable over the phone; my business French is very limited). This is likely due to a couple of factors – I’m now comfortable in life with a good career (and less stress than at the accounting firm) and several children. I’m way more self-confident than I was even 5 years ago and I believe strongly that having young kids and putting the focus and emphasis of life on them and not on yourself mutes the stuttering anxiety. That, or the constant lack of sleep numbs you so that you truly just don’t care after a while. Seriously though, I had pretty much forgotten about the terror of making phone calls until reading your post. I’m so happy that it’s no longer an issue for me and I wish the same for you (and all readers who share this pain).
