I don’t want you to panic but I’m not the person to talk to - I’ve never been sexually assaulted and I have very little experience with dealing with the topic. If you know somebody that does have some knowledge or experience with this, I would suggest speaking with them (in person, if you can).
The best I can tell you is to not feel as though it’s your fault. The belligerent actions of some other person are not the product of your own doing. I’m sorry I’m not much else help, and I really wish I knew what to tell you or what to say to help.
It may not mean much, but I do care about your well being and I hope you’re able to find some proper help with this. Again, I’m sorry for not being a lot of help, but I do hope you stay strong and if there is some way that I can help, absolutely feel free to contact me about it, even if it’s just to talk stuff out.

I’m sorry there aren’t more; these are just some of the help resources I’m aware of off hand. That anon should know it’s not their fault and that help is available to see they overcome whatever happened.
