PTSD indeed.
Many fans are too young to have experienced "Wide right", "Music City Miracle", those and the most recent "13 seconds" has left a lot of us too afraid to hope.
Some ridiculous fluke or twist of fete swoops in and again leaves us in total shock and disbelief that victory was snatched away, yet again, in the very last moment.
Perhaps some of us just care too much and the disappointment is too crushing.
