What do you do? You wait. And try to take care of yourself as best you can, until the next session when you talk about it, if possible. If she isn't open to talking about it then she isn't a good therapist in my opinion. Lostislost is right, it's not your job to keep the boundaries, it is hers, and I agree that is what it sounds like she is doing, though a simple email back to say that she can see you are hurting, and that she is there, but that this needs to be talked through in session wouldn't hurt, again, in my opinion!!!
Even a response like that is insanely difficult to bear, so I can't imagine what you are feeling with just silence really, but I have definitely felt all sorts of deep and dark and crazy feelings along this journey, so can relate a little maybe. Please keep safe. Wrap up in a big blanket. Sleep if possible. Eat a healthy meal or go out for a walk. They sound trite when you are in the depths of it all, I know, but maybe something will help. Honestly, waiting is the only thing we really can do!!
