Would you say overall it was worthwhile? My T suggested this a while back and I was very resistant (actually I was a little p***ed at him for suggesting it) but that's because I have issues around not being listened to or taken seriously back from when I was "just a kid" so being perceived as immature or childlike can be triggering for me.
I use expressive art a lot and I think that's partly why he suggested it.
Was there something specific about the sand tray that allowed you to express yourself in a way that drawing/painting/writing couldn't? Would it have been better with or without the therapist present?
