Most schools still put the heaviest emphasis on GPA and LSAT and it is rare that other factors are strong enough to override stats that put an applicant out of the running. At the end of the day, they want to know you have the academic rigor to make it through law school.
No worries! Each school will specify what qualifies for their particular categories on their admissions websites. We don’t have any URM considerations like they do in the USA, if that’s what you mean. As long as you can prove that your mental health affected your grades in a measurable way, and that since you’ve sought help your grades have improved, your claim is legitimate. When it’s time (not now, they are super busy with this cycles admissions), reach out to the admissions teams at the schools you’re interested in. They are very helpful!
