Adults in admissions know that while students think they have licked a mental health issue, they often come back. And colleges want to avoid that on their campuses. It does not help your application. You may still get in at schools hurting for paying applicants. But it weakens your app.
It has nothing to do with forgiveness. It has everything to do with wanting to admit students who will finish their degrees, won’t use tons of health center resources, and won’t have breakdowns or worse on campus. Colleges are businesses – don’t forget it for a second when applying.
