Therapy is personal and private. I don't care to share much. And those who aren't in therapy often don't have a realistic understanding of it.
I once told T about a family member who thinks therapy is a waste of time ("take a pill !!"), and she said "Oh, family never 'gets' therapy.". I think she's right and I like keeping it between her and me. It's definitely on my mind a lot, but I don't talk about it. I think about it and / or journal my thoughts.
