Just make sure she eats and drinks regularly. Let her sleep if she's tired. And...if she seems out of it or...lost? Maybe like a panic attack starting? I'm not sure how to describe it. If she starts acting weird, you should get away fast. I don't want her to hurt you you getting hurt. Also, sometimes when she gets like this electronics can be triggering for her, so you may want to keep them away from her, or else they may explode get broken. Phones, cameras, computers, alarm clocks, etc.
