But how do you know the idea that soothes these worries about the end are just hallucinations of this cognition of ours hallucinating in order to keep us going, surviving, multiplying and preventing us from jumping over the next bridge? Just like the bees are just a way to cope and deal with this grave grave pain.
You've landed on the (non-)paradox of the meaning of life. The meaning is that there is no meaning, which means the meaning is whatever you make of it. The axiomatic truths upon which you base your life, your worldview, your understanding of reality are yours to define. What happens next is up to you and how you contend with your worldview vis a vis your perceptual experiences.
You can accept certain conditions on the world as given, but you can never know they're correct. You can decide on the meaning (and sense) of your perceptions and interpretations, and since that's all you can do, you might as well lean into it. Accept your (non-)fate and all will be clear to you(r habitual and critical understandings of the world).
This perspective is broadly described as nihilism. There's different ways to express such a philosophy, depending primarily on how collectivistic vs individualistic you ultimately decide to be.
I somewhat agree with what you wrote, though that doesn't sound like nihilism to me. Perhaps philosphers use the term differently. To me, I just hold the realistic view; the reality is that I experience my reality. Nothing more, nothing less. And I get to be clever with the "realistic" word choice too!
