<Insert here everything FreelanceWizard said and a mention to beards because why not?>
The only thing I'd like to add is that you should be very, very careful about how you play her. What I often see with this kind of characters is that the player is unsubtle and focuses too much on the tragic angle, making them too angsty and introducing mentions of their tragic past at every opportunity which, most often than not, other players will interpret as attempts at hijacking the scene/conversation/plot.
I don't have a formula to avoid those problems (besides "don't do that", I guess), but you might want to keep as a rule of thumb to not make your past come out more than in passing if the current scene/plot is not specifically about character building.
FreelanceWizard's idea of using some sort of 'schedule' for the character arcs is a good idea. I've roleplayed with characters that became or were very broken and, let me tell you, it's very frustrating to see them never come out of their dramatic state, or only get out of it to drop into yet another that is worse or similar.
Forcing yourself to be under the clock, so to speak, will help with that: you make sure the character is growing at a steady pace, and other players will see there was a development and be encouraged to follow the story.
