About half of my sessions are written because my words get stuck so badly that it hinders progress. At first I hated the idea of writing, and I still get frustrated when I need to, but it was such a relief to finally get some ideas out that it's worth it. My T is okay if his clients without mutism write, too, so you never know- maybe your T wouldn't mind! My guy does pretty traditional/classic therapy, so if an old fashioned style T is good with writing, the chances might be good for others.
