You're dealing with a lot of loss all at once...I'm sorry and I hope it gets easier.

I too had a not so stellar therapy experience. I felt that I invested so much of myself and didn't get anywhere with it (admitted I didn't give it a fair go...only about 6 months or so). I told her that I would not be back and didn't expand on that statement. I got about the same response you did.

I suppose I wanted what she didn't have to give. Whatever the reason, I was more hurt about the lack of care than I was about missing anything I could/would have learned.

I hope that, given some time, you can separate the feelings so that they're not one big lump of mess
I'm glad you have the kids to help you get through this. Keep posting.
