Wow, if you're depressed, don't listen to this one -- whew! It was interesting Matthew's comment at the top because it seemed to me that Mercedes knew the emotions she was portraying here, inside-out. Either that or she's one hell of an actress. Or both. I think both. 

Whatever the case, the entire plot of this thing is a woman tape-recording her suicide note, with her husband commenting on it now and again, and it's sad and bleak, with bits of humor that are objectively funny, but don't make you laugh. This is Mercedes at her best.
