My wife goes with me to both pdoc and therapy appts. She has a very strong understanding of my illness and has a very good feel for when something is wrong with me and can give my doc/therapist a prospective that I can't. She also asks a lot of questions that I never thought about before and she obviously has my best interest at heart.

She comes to my therapist appts because I like her to know what I'm working on with my therapist. Also, we've covered/worked out issues in our relationship. We've working on fighting, compromising, looking at the others prospective, etc. Also, it gives us a safe place to bring up things that are bothering us (things in general or about each other) in a safe place with a none biased 3rd party.
