This isn't advice you can take now while you still have this job, but may help you in the future.

I was an early employee in one of the companies in the late 00s/early 10s that became a unicorn. Early on there were frequently times that required one of us (early engineers) to wake up in the wee hours to deal with problems. After this period of time I developed symptoms where I subconsciously always expect phone alerts to ring or things to happen in the middle of the night and have trouble going back to sleep if I wake up (which I do a lot even before; am a bad sleeper).

After I no longer had that job the way I slowly recovered from that is to sleep with my phone completely turned off or outside of the room -- letting my mind rest at ease that I'm not going to be waken up by a call or alert. I had to do this for a long time for that sleep paranoia to go away for the most part. I've also held less stressful jobs for a long time for my mind to recover gradually.
