Changeling lore was surprisingly lacking in the show, so the fandom has picked up the slack and expanded on what we had to chew through over the years.

Things Chrysalis dislikes: winter, sports, winter sports and, above all, being bested by Celestia at winter sports. But when your trusty advisor says it's high time you took a day off, you do what she says, even if her idea of a vacation spot turns out to be a ski resort at Equestria's absolute north.
Welcome to Clarity Peak. Enjoy your stay!

Sniffles by Cackling Moron
https://www.fimfiction.net/
It's a fact often ignored by peons, traitors and other non-entities but true royalty does not get ill.

And while it might appear that she needs looking after, she doesn't!
...but you insist then she is wise enough to take advantage.

When Queen Chrysalis was defeated, she was blasted to the inhospitable Badlands. Separated from her army and starving for lack of love, Chrysalis is rescued by an unknowing pony who points her in the direction of the nearest town: Ponyville. As the battle-worn queen treks to the small town, she decides that she is tired of fighting a losing battle and would rather just settle down and live a normal life. But old grudges don't just lay down and die, and Chrysalis somehow managed to choose the one town home to all six of the ponies responsible for her downfall.

A Bug on a Stick by Orbiting Kettle
https://www.fimfiction.net/
Celestia was a filly living on an isolated farm with her sister and harboring dreams of greatness. Chrysalis was a black goo poured out from a screaming wound in the walls of reality, with a weak grasp on the appropriate amount of fangs one should have. Friendship was inevitable.
Stand and Deliver by Gulheru
https://www.fimfiction.net/
The cunning Queen Chrysalis is back, seeking vengeance upon all of the ponies! To fulfill her desire, but avoid unnecessary exposure, she decides to infiltrate the Crystal Empire and acquire aid from one of its very residents, by seduction, persuasion, or coercion if necessary. That way, she can plot away in safety, utilizing the fool until he outlives his usefulness!
Surely a professional and ambitious upstart with a shady background, who has just been appointed the new Imperial Tax Collector, is the perfect target.
… maybe too perfect?
