how would i know if i was suicidal? i often think about ways i could kill myself and sort of imagine myself doing these.. often think about knives and this morning woke up from a dream where loads of blood was pouring out of my neck - from a knife.. i dont think i'm particularly depressed as i don't cry much and am not off my food or anything, although i do have these weird obsessive thoughts.. this all pretty much started when someone i knew was killed 4 months ago, but saying this i didnt know them v well at all, so i dont know why its affecting me so much.. do you think i'm losing it? i sometimes also imagine myself killing other people which i find really disturbing and horrible.. i don't want these thoughts and feel sickened with myself.. would appreciate any advice etc
