I’m sorry you’ve had mental health struggles and an abusive home life. I would not divulge any of this on your app. You do have a 4.0 GPA, and you say junior year was particularly challenging, so it doesn’t sound like your mental health challenges are behind you. Are you getting help/counseling? Have you already sent in applications describing your situation?
I agree with the above if anyone mentions it, it should be your HS GC. Are they aware of this information?
