Many years ago l had a therapist that stayed silent alot. Unfortunately though she hadn't gaged that l was struggling to speak due to stress and needed her to prompt me. It was a nightmare, a lost hour basically. I still really struggle to talk to therapists, partly as l'm so withdrawn and partly just intimidated by opening up about shameful things. The last person l saw spoke more but sometimes interrupted my thought processes, so it's a fine balance between letting the patient express themselves and knowing when they've hit a mental block.
