With all the respect for your therapist, but I just need to LOL at somebody who, in the past, besides all the other things, texted YOU late at night cause she drunk too much (I clearly remember that one), only to throw in your face this boundaries stuff now that she feel like this.

I don't want to be too rude but according to everything you said she should have just choosed another career. You are clearly NOT the one who is in fault here. If she set/allowed so opened boundaries (which, on first place, is totally unethic) only to take them back cause she suddenly was not "in the mood" (which now is even worse), well, then she got some serious problems.

Also... I can't just believe how she treated you on phone after you told her about your mum... you were clearly shocked and in fear, was it really necessary to tell you she were irritated and such?

Sorry, but I think that she would deserve to be reported to her superior or to whoever gives her permission to be a therapist. And I also think, of course, you should find someone else before other damages are made to your person.

p.s. i'm sorry for your mum...
