It's nice to see you caring like that for her.

Speak to relevant school staff about her, try to explain the situation, even though it's personal and might be difficult. You might want to be careful what exactly you say to who though, teachers can be real assholes too. If there are any specific kids bothering her, maybe you could also talk to their parents and try to explain the problem. Again maybe not tell the full story in case it gets "exploited"... you have to sniff out if who you're talking to might just be an asshole and doesn't care.

I think you need to get her a psychologist. You talking to her is good, and probably helps, but she is genuinely traumatized by what happened... and a professional would probably do a better job as she would know how to deal with this kind of stuff better from experience. You say she's scared of men/boys, so obviously it's better to find a female psychologist. Maybe there are some available through the school for free? You'd have to look into that yourself. It depends where you live obviously. In the UK there are things like this available.

I hope she gets better at some point.
