Chopin, I'm sorry she cut you off over an email, especially with the comments she made. Most therapists really want emotions to come out, no matter what kind of emotions they are. Repercussions like that are not the way to encourage clients to emote.
Like Skysblue, my therapist is patiently waiting for and would be thrilled by any display of emotion from me. I'm too much in my head for his liking. I suspect even if I lashed out directly at him, he'd be cheering me on.
