Sometimes when the therapy reaches a scary point for the client, it seems the only solution is to leave. I've left when I was overwhelmed with the ideas that my t was suggesting. I've learned to stick it out through those scary times, because often it's the most helpful idea in the long term.

I agree with everyone else. It does sound like your t does care about you and in fact is quite worried about you.

You can always call and get your appointment back. Therapists usually leave their doors open.
