It does sound like there need to be some better boundaries on her part. Some personal things are probably okay to a point...I like to know that my providers are human and have normal lives, lol...but it sounds like she's also doing a bit of office-business gossiping, which is not okay, IMO.

As for her being an effective provider...it's clearly not for everybody, and it may not be the right job for her. But you shouldn't have to sit there and wait for her to figure that out. I hope you can find a better provider soon and that your mania ends soon without any further issues.
