I work with a guy who is really nice and has only been in our team (of 3) for three months. He has confided in me that he has suffered from depression in the past and that he's not altogether happy with the job he's doing now (he was moved from another team). Today I found him in the photocopier room in a terrible state, what I can only describe as hysteria. He's not coping with the stress and I really believe he's having a nervous breakdown. He's begged me not to tell anyone... but I'm very concerned he might do something IYKWIM. Am tempted to speak to the boss but at the same time I feel I would be betraying his confidentiality. Help! what would you do? I feel like crying myself
