Deli, if you don't want to see Austin-T before you've spoken to P-doc I think it would be okay to miss it. You have already told him that you won't be going, so you don't need to tell him again. You have effectively cancelled already, although he has chosen to keep your appt open for you. That simply leaves it open for you to make the choice to go or not go on the day. I really think doing either would be fine - whichever is the most comfortable for you.

If you feel capable of it you could send him a message to say that even though you won't be coming Tuesday you would like to schedule another appointment later. But then again, if you don't... you've already told him you won't be coming, so even though he is probably hoping you will turn up, I think it will be okay if you wait til after seeing P-doc.

Take care of you.
