"Realism"? That's not realism at all. If anything, it's just thinking impersonally and objectively, maybe even existentialistically on a micro scale. Just stop caring about these things and you will rest easier. Might want to stop or sooner or later that'll actually turn into an existential crisis.

Just get over it. Live and love life, don't worry about the little things or a "higher truth". Just take it at face value for what it is; so what if we're just organic assemblies of matter with what we call a "conscience"? Does it actually matter? Not really. Just go with it and have a good time while you can.
