I don't you sound crusty at all, rob. You sound tired. You sound like a man who tuned everything up to level eleven to address a threat and now that the threat has receeded and you've got things (more or less) flowing your way, all the pain and anger you squished down (because experiencing those emotions fully would take resources required elsewhere) is rising to the surface. Just like anyone in any crisis who holds it together until the crisis point passes and then falls comprehensively apart. I think it sounds like a very normal human reaction .... maybe even a natural and necessary part of this process ... but not necessarily an indication that it's not worth it to persist.
