I don't mean to be dismissive about your experience; we all have a hard road, and some much harder than others. Still, if we're talking about it honestly: Why should the admnistrator and other people have compassion for you if you don't have it for others? I'll bet that, not being saint and under all that stress, you weren't perfect in what you were doing. I'll bet the administrator and others were also under many different stressors like you were; who was understanding them?
The only way there is compassion in the world is when it's between stressed people acting less than their best, often much less. If it's restricted to near-perfection, it wouldn't exist; the word 'compassion' wouldn't have any usage or meaning.
But that doesn't mean I do it well all the time. And I'm a jerk too and I hope people have compassion for me.
