Yeah, I'd expect my T to tell me beforehand. IDK, why she didn't, yet again she messed up...
I have no idea how it works with life coaches (guidelines ect), so I can't really say whether her relating to you is well within or far beyond them. I see, however, it is really hurtful to you. I do believe you would benefit from a more structured RS with her/real T.

A question - I really don't know the answer to but would like to: is life coaching even considered helpful for "real" mental issues? (I really don't know how to phrase it better, I mean no offense to anyone.
