Fellas are acting like they're in recovery...
This is basically how I felt during the times when I worked/studied, the same pain and suicidality but now you feel pressure to put in effort and burn energy you don't feel you have. No motivation, don't need the money, just want to die, have to be around normies, etc.
I haven't managed to cope with it yet, but one strategy I used was to remind myself that it's not really worse moment-to-moment to work rather than sit at home and be depressed. Maybe that can help you a bit, idk.
