I've emailed or texted my T when I have taken a break. I don't usually just take a break unless there's been a series of issues leading up to that point. Then I just briefly send her a text or an email with a short explanation why. The only time that I didn't explain why I was ending therapy was this past Wednesday. I think she already knows due to our issues via text. Once I mention the word "break" she won't respond. Anything I say after that doesn't matter.
