If you're referring to the finale in the Tractatus, then I'd recommend you spend some time with the late Wittgenstein, like On Certainty or perhaps some of his letters to Drury, e.g. https://externalword.blog/2013/10/19/ludwig-wittgenstein-let... .

Infamously analytical philosophy quickly turned out to be a dead end and led them to metaphysics to try and salvage their community.

Being and Time has a lot of interesting material but it is ill advised to approach it without having spent quite some time studying the philosophical tradition from Plato up until Heidegger himself, including Nietzsche. The old nazi presupposes a firm grasp of this history of ideas and makes an attempt at a 'reboot', which unsurprisingly turns out rather inscrutable without this background.

As for traumatising, in my experience Heidegger just lays down some groundwork for Derrida and Baudrillard. They're seriously efficient at questioning the foundations of language, thinking and society. Though I'd sooner recommend Merleu-Ponty, whose phenomenological achievements are more accessible and more easily applied in everyday life.

One could make the claim that some knowledge and experience does not fit into language and writing, the primary vehicles of philosophy. Here theology is a long tradition of approaches to such knowing and experience, which tends to be more foundational than the problem domains of philosophy.
