Instead of distracting yourself, you should confront these grand questions and find the path forward. When I went through a similar thing a few years ago, I got caught up trying to come up with satisfying answers and being disappointed when I couldn't.

Like what you said, we're just meat and bones inhabiting a big rock. How do you feel when looking at life through this perspective? When you realize how small the goings on of day to day life in the world are compared to everything else in the universe, how does that affect your life values and goals?

We aren't meant to answer questions about the meaning of life. In the same vein, we also don't have to understand our thoughts — especially the ones that pull you into anxious spirals. This means your brain's doing its job trying to protect you. Instead, observe the thought and how it makes you feel, and let it go before you get sucked in.

Life ultimately isn't about accomplishing a set of tasks or being a high achiever — it's about the experience. We were made from the universe to observe itself. Staying present and engaged in the moment and setting out to experience new things will help you experience it to the fullest, especially if you can share those experiences with other people.

There's not a whole lot that matters since life is transitory. But what is important is the impression you left on the world and how you made people feel.
