Riley,
Lets talk about this for a minute. You were violently assaulted. You were violated and raped. This is beyond wrong sweetie, It is evil. Remember this, you were treated with evil by someone you loved and called friend. Beyond that you are alone and feel abandoned by everyone who matters. It doesn't get much worse.
So what to do?
First, it isn't your fault. You did nothing to warrant this. There is no excuse or justification that can be put forward that has any validity. Did he even apologize? Even if he did it is inadequate. It is insufficient. Whether you go to the police is your decision. I would, but I'm not there.
Second, You are your best resource. You deserve to be happy joyous and free. What do you need to do to get there? Feelings of abandonment do not leave without action. You are beautiful, there is a place for you in this amazing world. If I was closer to Long Island that 3000 miles, I would be there for you now.
Even though you don't know me, I know you. I have been you. When they put me in 72 hour hold, I was with people who were hallucinating, and completely scary. Nobody talked to me. Nobody!! I have never been so humiliated or angry in my life. I told myself that the next time there would be no asking for help, there would be no witnesses. I'm grateful that the next time there were people, that someone was paying attention. 0kay, you have my attention. Send me a note and you'll have my phone number. Use it! I love you.
Third, Be gentle on your soul. The anger, pain, fear, sadness will pass. Not all at once, but it will pass. Who is nearby? Do you have a counselor? Do you know other trans people? We are everywhere. We exist, and by and large exist for each other first and always.
Fourth, Breathe, gently and intentionally. When the panic comes breathe. When terror comes breathe. When all is lost breathe.
I wish you peace.
Julie
