You have to remember, due to trauma we don't know about she's been (by my guess anyway) emotionally stunted. Literally a "blank slate" almost. Thanks to everything thats happened so far she's becoming aware of feelings and emotions that she has no real experience with and likely (most importantly) doesn't fully understand how to deal with or appropriately control yet. That's my take on it tho, so take it with a grain of salt lol.
