Dear T,
I'm sorry I worry you. I'm sorry I'm not more together. I'm sorry I make it so difficult to secure other services. I'm sorry I'm "that" client. I really don't mean to be

Dear T's supervisor,
I'm sorry you are left fielding his emergency calls over the weekends and after hours. I'm sorry I'm such a handful. And I'm sorry I could not bring myself to ask them to keep me there longer... you have no idea how awful the experience was. I'm sorry I ever complained about the place you recommended. While they were crap compared to what I am used to, they were miles above this place (at least they cleaned and checked in with me)... I want to promise to be a good little girl and keep things in check and do all the right things, but I don't know if that will happen, so I'll just say I'll try. And I hope not to piss both of you off at me. I'm sorry I'm "that" client...

Dear both of you,
I wish I had access to something that worked. I wish the depression lifted instead of got worse. I wish I had not screwed up the state benefits, because not only would I be able to pay you more for all your work, but I would likely have been able to get into a better place this time, and gotten at least a shred of help. But I suck, so that did not happen.

And finally, exactly what Mapleton said...
