Ugh, terrible sessions are so hard to deal with. I had a doozy of one a couple weeks ago.
These feelings are going to pass. It helps me if I let the feelings be what they need to be, without getting caught up in wanting to rage quit, feeling like its going to be like this forever and I might as well give up on everything now etc. When I am able to let myself ride them out they have usually eased way back by the time my next session rolls around and I can address the things more calmly.
She will answer your emails. I know its an anxious wait. She will get there. These feelings are hard but they will pass... all feelings do.
