There's an old saying: You can't care about the problem more than the customer.

In this case, since you are an employee, the customer is your company. You are providing a service for them.

If downtime can be fatal, and your company is large, they should actually hire some people to cover that time. You've taken too much responsibility upon yourself. You're caring about it more than they are.

You need to put your health before the health of your company. What do you think will happen to this company if you are unable to continue at work? They'll have to find someone else. Tell your boss that your boss needs to mitigate this risk by hiring additional staff to share the load or cover nights. You will help train.

If you don't think you can have this conversation, it's time to find a different job.

I see many of my friends falling is this trap, that they care way more about the company cares about them. They seem to believe that if they dedicate their lives to a company that will be rewarded. It might be, but they might as well be made redundant.

They keep giving but the company rarely gives back and this hurts their mental health.

So care just the right amount. And put yourself above your job. If you can't do that you need to find another job or rethink how you are doing your current job.

Not OP, but thanks for saying this. I think I care too much too often.
