Am I not allowed to rest?

Been working as an HR for a while now. Something about this job makes me want to let it go but the knowledge that I’ve gained through my previous experience keeps me here since nakakapanghinayang mag let go lang. One thing that I keep noticing with my previous jobs is as an HR, am I not allowed to rest? I always find myself mentally working all week. Stressed has been piling-up. Working on disciplinary issues becomes non-stop. I’m tired but I feel stuck. I want to let go but where will I go.

We have an issue at work, where they want to terminate an employee for multiple reasons in relation to their attitude towards work. But since we don’t have existing policies and all these are undocumented, no prior IRs have been made against them. But I still have to terminate them and I keep wracking my brains, not knowing what to do. It’s stressful af.
