Ask HN: How do you handle the stress of impacting users?

I'm in my mid twenties, I work as an engineer writing software for a product that is used by dozens of huge multibillion multinational companies. I'm not even working on something that big compared to a lot of unicorns/FAANGs. I'm responsible for a few major features and work +/- on every part of the product.

The product itself is not critical to most of our clients but every mistake I make, has the potential of angering thousands of people, ruin some people's day and making the company loose a lot of money.

As we grow and take on more big clients my stress levels are skyrocketing.

How do you handle this kind of stress?

Sometimes I just want to give up and go live in the woods.
