She has lost 10 lbs. in the past month and states she has no appetite. Kristin reports nightly sleep difficulty, both falling and staying asleep. Her mind just can't seem to relax enough so she can sleep. She has tried melatonin and the Calm app mindfulness techniques; they help some nights but not always. She endorses having difficulty focusing for long periods, and she has missed several days of work within the past month due to her symptoms. No hallucinations or delusions are voiced. She states "The only thing that makes me feel better is shopping online. I love getting packages every day." She is not experiencing financial issues from online shopping, but she has depleted her savings account.

She denies thoughts of self-harm or suicide.
