No emails on weekends? :/ Psssh! If she doesn't want to get emails on weekends she can just not check her work email on weekends.

What is it with therapists being unable to handle their own stuff? An email is something you can choose to open and respond to in your own time frame. I'd understand no calls on weekends, because that's a form of communication which does intrude, but who cares when you send an email?

Also, you're allowed to call... until she realizes you've hit a boundary? So she's basically blindfolding you and letting you wander around until you hit an emotional electric fence?

That's massively irresponsible, given your situation, Scarlet. You need to be told what the boundaries are and they need to not change. You don't need someone who is going to make you guess and then change them as she sees fit based on her mood that day if she decides that you have found one.
