I keep wondering, whenever I'm feeling bad about something, like stressed out or something negative happened or whatever, a thought, almost like a voice, but not a voice, in a chanting way says 'why not just die' or 'just kill yourself' or 'I want to die' and it's like, brain I'm upset enough! Why are you suggesting these things? Why doesn't the brain say 'why not get a brownie' or 'why not watch a nice movie' but no, it's about suicide or cutting and I haven't self harmed in over a year and I haven't attempted suicide in over a year but the last attempt was just while I was feeling very very stressed but there was no exact trigger, just my brain's chants suddenly got hold of me. 
The thing is, in the past, my ideas of suicide were around a kind of way to get people to pay attention or to love me or care for me, and I thought about it 'logically' but the chanting in brain isn't like that, it's just there almost randomly and annoys me more than anything because it's not something I actually want to do or think about ? It's like there's a little man in my head who comes out when I'm stressed and gives me those suggestions at the back of my head.
It just doesn't seem logical for the brain to do something like it when things aren't even *that* rough, it's weird..any thoughts?
