Diagnosis

It's one thing to consider, analyze, and research, but a diagnosis is another thing altogether.
You can look at medical websites galore, comparing listed symptoms and comparing your memories to what shows up, or you can read tons of biographies about people with X condition and match your life to theirs.
But a diagnosis is something different. It's real. You can't make it appear and disappear to fit the circumstance, like you can with personal diagnoses. You can't argue about how serious or trivial it is. It's defined, measured, and sure.
It's no longer just a tendency to complain about when the Me Monster game gets started, it's a serious trial that has to be dealt with.
