Yes, I also agree that "Pull yourself together" would be better here. There's also something I just noticed: shouldn't it be "A trash can overflowing WITH canned and frozen food." ?

Regarding the verse about destiny, the point is that fate did everything to seperate them, and it succeeded through all the misunderstandings. I feel this aspect gets lost in your translation. I'm not sure how to explain... "ça n'a pas loupé" seems to be missing somehow.
As for the line about pride, the original phrasing is unusual, but I think the current translation is in fact correct: there was the misunderstandings, and the pride issues came on top of that and didn't help either. "Not to mention" feels right to me here, or maybe "Let alone". "Without the will to take up their pride problmes of pride" would rather mean "À ne pas vouloir parler de leurs problèmes de fierté".

On a side note, I was wondering why you'd translate "en veut AU destin" as "is mad at HER fate". This nuance doesn't appear in the original text, its litteral meaning being that she's mad at fate in general, like you would be mad at life. I may be missing something here, though.

Oh, thanks for the kind words!
Yes, apparently "overflowing of" is not as weird as I thought, so thanks for clearing it up.

As for the rest, thank you for explaining your train of thought. It's very interesting and I understand the logic much better. I hadn't considered things that way, especially "ça n'a pas loupé". I find it really brilliant!
To be honest, though, I never made the connection with "loupe" (as a magnifying glass) in my entire life because "louper" has a completely unrelated meaning. "Louper", in fact, means "to miss", "to fail". You got me wondering so I looked up the origin of the term, and it comes from the word "loup", which doesn't mean "wolf" here, of course, but "defect". Anyway, "ça n'a pas loupé" is a common expression that literally means "it didn't fail", and implies a notion of inevitability, e.g. it was to be expected given the circumstances. That's why I was going for "sure enough", but I get how you ended up with "not looked into".

About "Sans vouloir", I hadn't thought of it that way either and, while using "vouloir" as a noun is definitely possible, I think it's a mistake here. The french line doesn't really make sense if you do that. I can't explain why as I'm really not good with grammatical terminology. It could work if you changed the context or the grammatical structure, but if you keep both it just doesn't. In fact, I think it wouldn't work in english either as it seems to me that, in this case, "sans vouloir" should rather become "without will", and I believe you'd see the same problem emerge.
However, keeping "vouloir" as a verb, it could still be translated as "without the will to"/"without wanting to". But the thing is, in french, we say "sans parler de [quelque chose]" as an equivalent to "let alone [something]"/"not to mention [something]". So "sans VOULOIR parler de" could also be a variant of that. Given the previous lines, I think that's the case, but that's really a matter of interpretation.

In regards to fate, I think I'm getting the idea. Things get a bit tricky sometimes, so thanks for the explanation! Well, thank you for the whole comment, really, it was truly interesting! :)
