"Being" a nihilist is kind of a weird idea anyway. It's more a feature of (parts of) various other world-views or approaches to certain aspects of philosophy, than, like, some thing all its own. Pessimists, broadly, are closer to a real definable "school" to which one might credibly assign hypocrisy at failing to follow through and off oneself (though there are various valid reasons that may still not really be fair). A famous example of this kind of philosophy in pop culture is Rusty in True Detective, who explicitly labels himself a pessimist, and who carries on not because he believes there's a reason to that he could defend philosophically, but because he "lacks the constitution for suicide", as he puts it himself. Though, again, even the pessimist school comes up with justifications for going on living (they just tend to lean more romantic, than couched in reason). TL;DR I think you're wrestling a ghost with this true- or not-true nihilist deal. I think the colloquial use of the term admits cases and views less-strict or precise/complete than you're insisting on, usually being a shorthand for some limited and specific case of nihilism (e.g. existential nihilist) that doesn't necessarily mean what you're expecting nihilism to mean, while some more-formal-and-strict version that exists as an all-encompassing School of Nihilism isn't really a thing to begin with.
