First of all, I'm so sorry this has happened to you. You didn't consent. It's rape.
Regardless of what else you do about, I encourage you to contact a rape counselor. The after effects of rape can last a long time and do a lot of damage. A rape counselor can help your process what happened to you, and counsel you regarding what you can do about it. You can find something local, here:

In addition, if you're in school, your university may have on campus resources. I urge you to look into them. Again, I'm terribly sorry this happened to you. If you need someone to chat with, feel free to PM me.
