I've been through a shit ton of trauma, and I'm at a place now where I will decide before crying, "Is this worth the inevitable headache?"
Which leads to me saving up several sadnesses and then planning a luxury cry sesh where I take a preventative ibuprofen, drink preventative water, listen to sad music in a shower and really indulge. Apparently this is abnormal and unhealthy but I really, really hate getting a headache.
If something is sad enough to justify the headache, of course, game on but I will complain!
