You are an adult and can do whatever you want. She may not read it, she may not want you to send her emails but that's her point of view; you can send her emails, accept whatever consequences because it is what you have chosen to do. That she wishes you did not send her an email is not a murder, it is still just an email. If she states how she feels, that she wishes you would talk to her instead of send an email, that is just how she feels, what she thinks would be good for you and your therapy, not her being "mad" at you.

You are angry at her, that does not mean she is angry at you (for sending an email or anything else).
