Why do you think people have suicidal thoughts? Is it reasonable to result to potentially killing oneself to be able to remove the pain a person is suffering from? What are your thoughts about this matter, is it acceptable or not? Why does a person result to thinking of suicide? How can you help the person to change His/Her mind?
Negativeity and negative people , stay away from it !Sometimes that's just not possible.
Of course, in general, you should be surrounded by positive things and positive people and that can definitely help people with suicidal thoughts to make them feel better.
But sometimes you just have to stay in that negative surrounding... And then, if you're mentally unstable, that can really cause some drama.
A colleague of mine suffers from depression and once she told me a lot about her condition... Oh boy, it's some really serious sh*t.
