also, when you do need therapy yourself, depending on what kind of therapist you get, you can end up spending a lot of time learning just for your own sake. my brother did that, and at some point he was able to explain his issues better than the therapists he talked to.
did you ask your wife about her reasons to become a therapist?
On the other hand if you happen to have a condition that doesn't respond well to therapy it seems kind of horrific to me to become a therapist just to learn that.
yes, exactly. english is not my first language, so maybe i am not applying the right terms. either way i think is easier for the therapist to understand their patients if they themselves feel that there is something different about them.
