I feel exactly the same.

Me and my friends are really close and a few of them are aware about my self harming, but seems like they just ignore it. Even though I know that they'd be there for me for ANYTHING, I still feel I have no one to talk to. I think the reason why they dont seem to bring it up to attention is because either they are frightened themselves, scared I might not want to talk about it or simply because I put on a show in front of them and make them think I'm ok (when actually I'm screaming for help inside).

Any of your friends who know about your situation, maybe it would help if you explained to them that your not doing good and to show them that it is ok for them to talk about it to you openly. I recently let my boyfriend know that he can mention it anytime and I have to say it helps a lot more because he regularly asks how Im feeling now and brings it out into the open and gives me a chance to talk about it.
By doing that Ive gone from thinking I have no one to talk to and that no one cares about how I am coping, to having someone to bring it up every so often and it truely does help me
