You can’t control the comment section. You can control whether you scroll it at midnight.

You cannot moderate what strangers say, and trying to will eat your week. What is actually yours is the timing and the amount: whether you go looking, how often, and at what hour. Late at night is the worst possible condition for reading an opinion about yourself, because everything lands harder and nothing can be argued back.

Set a time after which you do not open it, and make that earlier than you want to. If you are going to read, read in daylight with something to do afterwards. Taking the app off your phone for a rough week is a reasonable move rather than a dramatic one.
