My T is gestalt-based, so the empty chair technique was something he encouraged me to do early on in therapy....and I couldn't bring myself to do it. My discomfort with the embarrassment of the idea was the main reason...but underlying that, it was an incredible fear. He initially suggested that I use the technique to talk to my dad who passed away a few years ago...and just the thought of my dad sitting there across from me created such a surge of emotions. So, it's likely a credible technique and I'd imagine that it'd be helpful to me - if I could get over the embarrassment of it.
