There's very much a whole theory/literature around queer time (see the reference to Muñoz in the article) -- being queer frees you from this sort of linear heteronormative progression through stages of life. This JSTOR blog post might be of interest. The argument isn't that this sort of non-linearity is specific to queer people (see the bit in the JSTOR post tying the economic precarity of millenials to the notion of "adulting"), but rather that it is an extremely common queer experience precisely because the markers of "progression" through life are heavily rooted in hetero- and cisnormativity.
