Awful pro-life propaganda at best, trolling at worst.
I agree, first I thought this is a good video and then they start talking about how suicidal people are glad they didn´t succeed in killing themselves, why would any real suicidal person be glad about that? It just means they have to keep suffering.
Also did they say this guy has suffered from depression and suicidal thoughts for 35 years and yet he remains hopefull, that is just delusional at that point his whole youth is gone and practically half his life too but he still remains hopefull. If you take this video into account (just a few minutes about the graph) then it makes even less sense since if he magically would recover in the future he would have suffered the most of his life just to have a few good years.
