i think this is positive. because it means therapists can empathize when people feel that there is something wrong with them. there is nothing worse than a therapist who doesn't take your feelings seriously.

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?
