The depression and trauma disorders they suffer from is totally biochemical over time.
People seem to think if someone loses it and kills themselves, its the same sort of "depression" a little kid experiences when he looks out the window and it's raining so he can't play baseball that day.
They are not cowards. They are ill. They can be treated but the ignorant shit they have to face when trying to do so deters them from getting the help they need. Hopefully one day people will stop with the stigma against a person who's chemistry is thrown off. You wouldn't call someone with cancer "weak" or a "coward".
It's never a rational decision someone makes cuz they're having a less than perfect day. It's an illness that needs to be treated and not mocked.
I'd love to see the people who call them "cowards" trade places with them. I'd love to see how they'd face every shocking aspect and spiraling sense of hopelessness and "just be brave". Not to mention the drugs they could be taking have to be totally monitored by the week. The drugs alone, could have the complete opposite affect and you'd be surprised how quickly a person can feel complete doom when their brain chemistry is adjusted the wrong way. Everyone is different. There has to be room for changing meds and seeing what works for different people.
Walk in someones shoes before you stick a label and judgement on them
It's obviously a little more complex than being bummed out one day.
