Hi Abby,
I am sorry this this was such a hard session and has been so hard for a long time. I have to agree wiith the others (torn mind and MKAC) I think your t is avoiding responsibilty and placing it on you and unfairly so. From you have wriiten so well here it sounds as though you have done a lot of work on yourself and are now discovering that your t is not supporting this or giving you the tools to deal with the therapy hangover.
I would not let her place the blame on you and tell you you are not wanting to get better. This is just her opinion, it is not a fact or something you should take any notice of since it is clearly not true. Maybe the truth is that you can't change right now, that you are stuck and it IS her job to help you get unstuck and that is NOT asking too much from her.
Have you thought about trying another type of therapy such as CBT to make you more aware of your thoughts and to try and help you change them?
