Good call on avoiding daddy dearest at this time, you're looking after yourself, and that's a wise thing to do. For what its worth, your trigger doesn't sound silly or petty in the least, I've been known to go apeshit and have a meltdown over lost or broken irreplacable things, add family drama to that, and YOU my dear sister are handling it swimmingly. I mean, to show up and stay at work in that state? You really are a warrior I'm thinking of you, and hope you find the release you need
