Sorry it gets you so tied into knots, Silent tsol. I'm glad you were able to email her! That said, I really don't think it isn't being too clingy or demanding to say in your next session, "So, can I make an appointment for next week?" Believe me, our therapists are there to support and encourage us and asking for what you need (another appointment) is not too demanding.

I think you might be overthinking this or expecting your therapist to "mindread" that you want another appointment. Consider putting it in your head for your next session that you WILL ask and book another appointment . . .but only if that's what you want
