I don't think any other human being, T or not, could really truly understand what anyone else is going through. I mean, how could anyone?! Nobody else can walk in your shoes and be, or know, you as well as you.

It is not because one is a T that they magically have the key to understanding us.

The most a client can aim for is to gain their... empathy? validation? support? strategies or tools to break free of patterns? But that's about it.

Now if you mean you feel totally alone and T shows not an iota of understanding, then I would say it is high time to switch Ts.
