I love the way Bucky deals with his memories in this by dissociating and describing images for Steve to draw. It's an interesting take on recovering!Bucky that I can imagine quite easily.
I also love, as the OP pointed out, that you give us two very different perspectives on the same scene.
It is interesting that Bucky wanted to stop existing when he realized that he was the only one who cared any more if Bucky Barnes was Bucky Barnes, and that he decided he wanted to be Bucky again when Steve remembered him. We're often told (in the US, at least; I can't speak to other cultures) that we are supposed to be entirely independent and not care what anyone else thinks. It's useful in some situations, but not entirely practical. Humans are very much a social species, and it is nice to know that other people care about you. So on the one hand, I want this Bucky to recognize that he has value independent of Steve believing in him, but on the other hand I can completely sympathize with him deciding not to exist as himself anymore until Steve came along and remembered him.
