So I Have This Friend...

And sometimes she makes me crazy! Ok, not sometimes. Always.
Now, don't get me wrong: she really is a great person. Her heart is in the right place and she does loads of chesed. But there is one flaw about her. It's all about her. If she did something for someone else, as nice and helpful as it was, she will martyr herself out to no end.
"I drove to three events this week! I didn't sleep but I like totally volunteered so much."
"I was the first one there so naturally I helped set up and was the last one there so obviously I cleaned the whole place, took out the trash, waxed the floors, and cleaned the toilets with my own toothbrush."
Ok, so I am exaggerating slightly. But only slightly.
Now, like I said, she is a nice person. But she is very me-centric. She has to be the best, spent the most, traveled the farthest, know more people, been there, done that at least a thousand times if not more.
And to be honest, it's starting to get to me.
So this post was half kvetch/half request for help.
How would you handle a person like this? How would you react to her endless stream of bragging and self martyrdom?
(To better illustrate this person, here is a video of a character she closely resembles in personality... I think you will get what I mean when you watch it)
