Well, you'll probably get what you asked for. He'll probably allow you to take a break and will give you that space. Be prepared for that. Is that really what you want or was it a knee jerk reaction to whatever triggered you in your session? If you don't really want a break, you will need to take the initiative to schedule a session and expect that this will need to be talked about. If you do really want a break, that's okay too, and still expect that you will need to talk about this in session. The one thing not to do is to use this as some sort of "test" to see if he'll come begging you to come back right away or something. Not that that is what you are doing, but own your choice to take a break or not as your decision and work from there.
