Run! Or at least go to your manager and make very clear that it is simply not possible to provide anything like 24/7 incident response when you are alone. That is the kind of conversation, where it is just better to get fired rather than not getting your point across. The basic structure of the admin job is, that there is always more to do and it is very easy to burn out. There is always more to do, it is always important, but trying to chase some ideal of a perfect system will just exhaust you. Furthermore, it is not a big problem to check your monitoring before going to bed or a few times on the weekend, but that limits your rest periods to a few hours at best, you no longer get a full weekend, and that will grind you down over time. So, manage your time and sanity, and importantly also manage the expectations of your boss and co workers, there is only so much you can do when you're alone.
