This can and probably does happen in your interactions with all people in life, not just a T. The fact is that all people have personal lives. What they consist of varies and it's guaranteed that it's not all good. Therapists in no way have perfect lives. They experience ups and down like anyone else: sadness, insecurity, relationship issues, loss, trauma...the list goes on. They can empathize with human experiences. You have no idea what kind of childhoods people have. People are multidimensional and career and marriage/kids is only part of it (lots of them are divorced by the way, as are doctors). If part of the reason you're in therapy is due to the issues you mention like lack of career, relationships then someone in the same boat as you may not be much help. A T is already at a disadvantage by default because they're employed. You'll have to avoid all Ts if that one criteria bothers you so much. Maybe you aren't jealous but perhaps a little jaded by experiences with others who've judged you in the past. This is the difference - a T won't chastise you or shame you because of your difficulties but instead try to help you overcome them. Another thing to think about is how a T can be a kind of mentor. It might be hard but will be worth it to open up to someone whose life you admire, if only a little.
