Without sounding rude to everyone... suicide for me is the most selfish thing I could ever do. What's wrong with wanting to do something for myself? Selfish in comparison? Well, it's about me(or the person), and not really about anyone else.
Idk, depends on the context i suppose when they say that. If it's a guilt trip? Meh the person saying it's selfish is an idiot, and thinks that living for someone else while you are suffering is acceptable.
Again though, a permenant solution to a temporary problem, that rings the truth in some situations. I don't want to give examples, but it can make sense to some peoples situations, where a moment or a few moments seem to blanket out the rest of the world and possibilities of life, and leave only dark emptyness and pain visible for the person to touch and feel.
Others, ... sorry. I donno. I kinda think it does apply to most situations actually. Without insulting anyone and what they are going through, there are better parts of life apparently.. even if they seem impossible to touch with, and the most horrible parts seem impossible to escape from. Sometimes the person suffering can not see or feel their way out of it, but others can help them out of it.
Nothings truly permenant emotionally, there are ways around it, and to deal with it. And the practical facts that kill us, there are ways of dealing with them too.
Sorry I guess it rings true, but just generally saying it can be so insensitive, especially when you don't know what the person is enduring.
I reckon people say it because they want to help or dont know what else to say. The problem is when they start spouting hallmark quotes without trying to understand the person who is in pain. Atleast, I think that's insulting. In some cases, it almost comes off like a cheap quick fix. But then again, the reasons for why they say it can be just as mysterious as the reasons for why someone suffering from depression says and does what they do.
Usually just a failure to understand eachother and communicate.
