I have a suggestion for you.
Write something like this in the first three paragraphs.
Early on my senior year in school, I got assaulted and was diagnosed with PTSD and ADHD, which consequently had an affect on my grades.......
And something like this somewhere around the last
And my experience with sexual assault has led me to grow immensely as a person and the way to deal in situations of crisis.....
I would highly recommend you that you don't write more than 100 words about that incident and keep it short. Tbh, they won't like to hear about that much, instead they just want to know whether you fit in the program or not. So you better focus more on that.
I wish you all the luck for your application and more power to you for overcoming all the challenges in your life! XOXO
