In my session today, T2 asked if I'd discussed my relationship with T1. I said not really, that T1 had talked about it, but I hadn't really said much. T2 suggested that maybe I write a letter about my feelings and give it to T1 at the end of my last session. T2 said he's often had people do that because ending therapy is so hard.
So there you go. My new T thinks it's a good idea. T's don't think emotional letters are stupid. The fact that he knows how hard it is for you to express those feelings probably makes it even MORE touching to him.
(Incidentally my reaction today was to start crying and saying no way could I be that needy. so I TOTALLY get where you're coming from. )
