I didn't understand the answer choices, so I guessed mine should be changed from "depends on the circumstances" to "yes" as I have permission and ability to contact our leave a message at any time, I just choose not to unless it's something that cannot wait. About 2 weeks ago I called a few times hoping just to leave a message but she had picked up.
If there's something that I want to let her know but don't need to talk about before the next session, then I write in my blog and just leave a message asking her to check it before our next session.
I'm sure if I became overly needy or crossed any lines, she would tell me. She also does not check her vm when not in the office, but the organization has a crisis line that I can call if I really needed to talk to someone in the moment. I have not yet called that number.
