I know I just saw you yesterday, but next Monday is a really long time away. I didn't feel like we got to talk about how I'm feeling now.

I want to text and ask for another appointment this week. Except... I can't take time off work to see you, and even if you for some reason had an appointment not during my work day... I don't really know what I want from you. I'm sad, hurting, depressed... but it's not new.

I visualize myself going into your office for an extra appointment: you start the session with "so what would be helpful today?" and I would just... throw up my hands, feel guilty for wasting your time, and really strongly consider leaving (but still paying).
