Your application is NOT a confessional. It’s an application for a position as a student. An admissions officer is reviewing your application to ensure you can succeed.
Rightly or wrongly, your post is full of red flags that might give them reason to believe it would be hard for you to succeed. Your grades are good. Don’t draw attention to something negative. It’s none of their business.
I agree with others that it’s a good idea to seek help to address your mental health issues.
