I'm so sorry for you. This is not how a T should react. If she calls these things harassment, that's just weird. I don't know what all those emails were about, but if it was just about scheduling or your therapy, then you can't really call that harassment. If she feels like you're breaking boundaries, then she should talk to about why you break them and what's behind that and such. But if she didn't even said there were rules about this and that, then she can't blame you if she feels like you broke them.

I also haven't been told by my T what the rules are about emailing. Now I don't use email that much, because I'm afraid to do it too much. Also now I'm in group therapy, I don't know if I can still use email for other than scheduling. T's should tell you the rules.

This is so not something a T should do. It really sounds like you're being punished like a kid. You are paying her. And you're paying her for therapy, for help. Punishment shouldn't belong in therapy, it isn't helpful. It's so weird she does this.
I don't know if she does this kind of thing also with other client. I wouldn't accept this. I would walk away from her. I can't imagine other clients would take that. But you're attached to her. I know how that feels. Even if it hurts or you don't feel the therapy is helpful, it's too hard to walk away. Maybe that's why she thinks she can do this to you, because she thinks you will stay anyway?
You should have another good talk about all this.
