Definitely not out of place, no worries there.

I'd suggest writing down things prior to your appointments. Obviously having your wife speak for you during your therapy sessions isn't a healthy way of healing, even if she is just trying to help. But I get the feeling of having so many things you want to say and talk about, but then walking into the room and just blanking completely. Therapy is very much something where you get more out of it when you put more into it.

A journal to just write stuff down in whenever it occurs is a good place to start. If you'd rather do a regular nightly writing session that could help too. I'm definitely not a professional by any means, this is just something I found to help me out when I had a similar situation.

Wishing you the best!
