If they're true friends that always stand by you and when you're upset and care about how you're doing etc then you should be able to confide in them with 100% confidence. The fact that you're worried about how they'll react and if they'll think badly of you worries me that you know they're not true friends or something. There is a stigma attached to mental illnesses because not enough people talk about them and don't know enough, and can cause them to reject those with mental illnesses. I know how it feels so I'm always here for a chat, I just hope your 'friends' can understand if you tell them. Don't forget to mention how hard it is and that you just need people to be there, cause when I told people they left, and that really hurt. Maybe tell one person that you can trust completely, after all a problem shared is a problem halved xxxx
