It occurred to me reading the Internet that there seems to be “points of pain” for most sports - events (usually game losses) so horrific that fans of that individual/franchise suffer some kind of negative emotional consequences just being reminded of it, even after years.
Obviously, what happened two Sundays ago is probably an example, and I know there are well known examples out there, but I thought I’d let those be mentioned in replies.
So what are yours?
Appalachian State 
18-1. 2003 ALCS Game 7 (still have never seen a replay of the Boone HR because I cannot bear it). The 2012 Champions League Final.
San Francisco Giants fans are only now getting over Game 6 of the 2002 World Series…except for those who still haven’t gotten over Game 7 of the 1962 World Series…
Hearing “Tuck Rule” or “2002 Super Bowl” will probably incite angry feelings in me for the rest of my days.
For this Ottawa Senator fan, the names Jeff Freisen or Jason Pominville still hurt.
Chicago Cubs: Steve Bartman’s fan interference game in the 2003 NLCS
Up 7 games with 17 to go.
Among New York Giants fans of a certain age, “The Fumble” will never be forgotten.
For those who don’t remember, it was the last play of a Giants-Eagles game, and the Giants were leading. All they had to do was take the snap, kneel, and go to the locker room with a victory. Instead, QB Joe Pisarcik tried to hand off the ball to Larry Csonka. The handoff was botched, a fumble resulted, and Eagles cornerback Herm Edwards (yes, the Herm Edwards who became an NFL head coach and an ESPN game analyst) ran it back for a game-winning touchdown.
That play embodied life as a Giants fan in the Seventies. In those days, no matter how good things looked, fans knew the Giants could (and would) find some way to blow it. NO lead was safe with this team! The Giants in those days always found SOME way to lose.

Sorry too painful to elaborate. Look it up if you don’t know
Game 6 of the 1985 World Series.
Game 7 was pretty damn traumatic, too, but Cardinals fans were too numb to care.
Even on TV, when Albert Pujols hit the bottom of the 9th, two out home run against the Astros in the 2005 playoffs, you could hear the crowd die.
The Yankees blowing a 3-0 series lead in the ALCS to the Red Sox, of all people.
Ugh.
The Baltimore Colts leaving town in the middle of the night in 1983
The Baltimore Orioles losing the 1979 World Series after going up 3-0
I don’t follow college football, but here in Mizzou country, you speak the words “Fifth Down” with caution.
There is a bar near my house called “The Fifth Down”. They have a big sign inside describing the infamous play. I always thought it was odd to name a bar after your town’s most painful sports loss.
The Catch (Football version)
I have to change the channel if they begin to show this lowlight, lest I become physically ill.
Francisco Cabrera
David Volek
Just… yeah… sigh
Forth and Twenty Six or Fail Mary. Take your pick. There are more as with any team and I’m sure when a name is put to what happened nine days ago it will join the list.
