Mrs. Weasley. I'll give you a list.
*Her husband got in trouble multiple times at work
*Her son got mauled
*Ginny married Harry
*Fred died
*A rickety house with tons of children
*Had to conspire with pottah
*Almost died on multiple occasions
*Husband almost died
*Sons dragged in the mess Harry Potter without asking
*Lived through enough trauma
*Worried sick as her family died dangerous things ALL for Harry Potter
*Her son lost an ear before dying; she got an exclusive look
And many more misfortunes like Percy acting like a dick. And her twins dropping out of school. And all of her children being redheads. And Ginny being in the chamber of secrets.
The point is I could ho on all night.
