I am sorry this happened to you. Here is my response on that same thread:
I do not think you should write about it. It’s a terrible thing to have happened, and I am not trying to minimize it. But there are SO many students out there who have suffered all kinds of awful and traumatic experiences. Many students come to this forum asking if they should write about their mental health issue, medical issue, death of a family member, abuse, parents’ divorce, and more. I understand 100% that these experiences are a huge part of who a student is. Many students will write about them no matter what anyone else thinks, and that is fine.
I strongly feel that most people are more than the bad thing that happened. I think that every student can talk about something that shows their resiliency and strength that is not just surviving the ordeal, and I think it is possible to do so without talking about the trauma itself. Are you a person who was raped and survived, or are you a strong person who loves yoga and painting? Be aware that no matter how you describe the incident/trauma/experience, it may sound as though you are trying to elicit sympathy, even subconsciously. Is it a bad thing to elicit sympathy, even if you aren’t aware that you are doing it? I don’t have an answer. Would it be enough to say “A crime was committed against me. This is how I coped and got my life back.”?
You came here saying you fully intend to write about it, so I do think you are looking for confirmation as much as advice. If you must mention it, I would be short and concise: “I was raped. The experience traumatized me, and this is how I worked my way back from it…” I think even three sentences is too many. I also think it’s best to show an aspect of your personality that is more than Londontola, The Survivor.
I sense that you are probably a good writer, so be careful in your approach. Give them a reason to want you on campus.
