She works as a teacher and was in a long-term relationship until three months ago. Following the break-up, she started to drink more and her meals became erratic. She has been recently diagnosed with anxiety. In addition, she recently broke her left ankle after falling while hiking.

Her regular medications now include sertraline, vitamin D, and a benzoyl peroxide gel for acne.
