As someone who's been suicidal, hearing some people say Suicide is selfish -- Are out of touch with reality.
People are assuming they just feel sad or anxious, but it's so much more than that. One way I can describe it is -- Imagine you haven't slept in months and it feels like you're being strangled all day long. You're struggling for air and to find the peace of a good nights sleep, but it NEVER comes, and it just keeps getting worse and worse and worse. You're terrified of how you feel, but you're even more terrified of how it's going to feel tomorrow. You've tried taking hard-core drugs to calm you down (i.e. benzo, alcohol), but it only provides a moment of relief and then the pain comes back ten-fold the next day.
Imagine the feeling you'd have if a doctor just told you that you had cancer. Now imagine that feeling every moment of every day. And what's worse, there's nothing actually physically wrong with you.
Imagine your mind turns on you and you're unable to control your thoughts. You start getting desperate for the pain and anxiety and depression to stop, but there's almost nothing you can do except pray it will end.
Most people who are suicidal are actually incredibly strong people who have been dealing with this a very long time. It's not that they don't want to live, it's just that they don't want to live like this anymore.
It needs to be talked about more.
