> I can't imagine e.g. taking some time on Sunday afternoon to feel that panic I suppressed from the crisis on Monday.

Almost literally that. Revisit the moments that made you "suppress" things. Think of it as a post-mortem. It won't be the same, an echo distorted by time and distance, But pay attention to what you set aside. Suppressing emotions is the short term hack. The ideal is to be able to have them and still be centered. Only way to get better at that is practice.
