If you talk about your take on something and it’s influenced by how you see the world, it’s fine. Something you realized about yourself while helping others, how you chose to put your strength into something. It sounds like your healing process has involved helping others. Something in that story could be very powerful - perhaps it’s the personal part of what you tell a schoolboard… What is important is that the story makes the AO think “this person would be a great addition to this community”. It sounds like you have the fodder for that. And make sure it shows who you are. So the story of trusting a teacher to help you (vs being the helper), the story of helping a friend with a problem that was huge to them (and perhaps trivial compared to abuse) because you could relate to someone experiencing pain, the transition from school as distraction to passion. Remember the essay is short, and you want the reader to come away feeling like you are awesome. You don’t see yourself as a victim- don’t let them either!
One other thing… You should ask your CC or one of your recommenders to write about this as it’s a defining part of who you are.
