Dear T,
I've made a last minute appt with you for tomorrow morning at 11. Please don't make feel like I've made a mistake. I plan on being completely honest with you as always, but I'm really scared to. I'm really afraid you may consider inpatient ED treatment after hearing what I have to tell you.
I should've just waited until our Monday appt and not taken this cancellation appt at the last minute. Feeling way too triggered and anxious right now.
