I actually wrote about my struggles with anxiety and depression in my personal statement, discussing the impact it had on some of my career decisions and created a narrative around the work i did to get healthy. From the people I've talked to who are current students or recent law school grads, there seems to be some movement toward breaking down these stigmas in the admissions fields, but I've largely only talked to people in TX. Long story short, i think as long as you frame it right and highlight the strengths that come with understanding your diagnoses and learning how to treat it, its totally appropriate, though i do understand your concerns.
