It's not the form that Alek is talking about that bothers her. It sounds like it's the wolf form she's had her her whole life. That part at least is comfortable. Familiar. That part she can handle.

It's the other part, the fact that her control on a full moon is being ripped away from her again, that this time she can't get it back, that's so much more devastating. Her body slumps again, hard against the lockers behind her, letting the edge of the metal guide her to the floor so she can rest her elbows on her knees and burying her face in her hands.

She's tired of people and things taking things from her that aren't theirs to take. She didn't ask to be this kind of wolf - she didn't ask to be in this Chicago in the first place. And yet she still has to deal with all the consequences.
