i cant speak for your therapist, but if it were me, i would be more sad than disappointed...as much as youre struggling with yourself and not being able to figure out what to do and not knowing how to go about getting better, i would be sad that you have to go through it. i wouldnt care about you "letting me down" as much as how you must be feeling with all that inner turmoil churning around and no spigot to turn that lets it out.
