To be honest, there is a real limit in what you are capable of doing for someone who is being abused. Seeing a counciler is good, at least she has someone to talk about it. But really what more can you do than be there for them and lend them an ear? I think you'll find no one knows because she doesn't want them to know, and you shouldn't try and force her to tell someone. I know it must be hard, watching a person tear themselves apart, but there isn't that much you can do

As both a teacher and also a welfare worker, your friend's counsellor should be bound to report what she is being told if she discovers that your friend or anyone known to her is in danger. It's called mandatory reporting. However, if your friend isn't telling her counsellor what's going on, there's nothing the counsellor can do till she sees signs of abuse. The thing is, what leads you to believe she's being abused? Cound what you perceive as being suicidal be depression? It's a tricky situation as there could be a number of explanations for her behaviour. If you are concerned, speak to someone. Perhaps a teacher, or even a parent. There's a chance she may not be abused but you still need to say something because from what you tell us, there is something going on that's worth looking into. I also think that because you've experienced loss through suicide it might be worth talking to a counsellor about how it's affecting you. You're clearly someone who cares and someone who is affected by this stuff and don't feel like you can't talk to anyone because it'll mean taking attention away from your friend. She has support via a counsellor, talk to someone for yourself. Whilst it's great that you're such a caring friend, don't make yourself suffer because of how much you care.
