there is a menu in the game where you can see all the tasks that are scheduled in the queue including stuff like "wash self" and "replace clothing", with targets and who is currently assigned. I believe personal tasks like "have a mental breakdown" are spawned already assigned and locked in to the dwarf they are relevant to. iirc its the (j)obs manager, the same place you assign automated orders like making more beds/beer if the stockpile ever has less than 4 etc
