My roommate was raped.

Just like the title says. My roommate was raped last night. My other roommate and I helped her the best we could by washing her bedding, giving her comfort, etc, but she's so upset. I just wish there was more I could do. And I should have been here but it was the one night I went home. My mom just ordered both of my roommates tasers since I'm the only one that has one, but is there anything else I can do? She's currently watching Netflix and her eyes are red and teary and I hate seeing her like this. It breaks my heart.
