No, and I think anyone who does is being a jerk.
I always hate it when people say, You know, your problems aren't that bad, oh, your parents only fight a little of the time, or something like that. The people who live by this mantra better never ever get sad, because you know, there are starving kids in Africa. No pressure or anything.
Everyone's problems are real to them, and if someone thinks their life sucks enough that they don't want it anymore, respect that and realize that in some way, these "minor problems" are clearly the biggest deal ever to this person. It takes a lot of subconscious mental gymnastics to get to the point of suicide, because humans are animals and animals are evolutionarily hardwired nnot to want death. Maybe it's brain chemistry; maybe it's something else, but No one just wakes up one day and consciously decides, "You know what the best way out of this problem is? I should die! That way I don't have to deal with anything." It's a hair-tearing, soul-sucking, life-consuming concept, born out of desperation and the inability to see any other way out. It's not an "easy way." It's an "only way." You can't call people a coward for not perceiving something, or not being able to viscerally understand at the time that yes, there are better ways. Understand that these people aren't doing this for the hell of it; they honestly do not see any other option, and not because they consciously decide not to.
I honestly think that "teenagers wanting attention" makes up a negligible percent of suicidal people. Some of that can be interpreted also as "I don't know how to help myself now, so if I'm loud enough other people who know what they're doing will try to help." That's not attention whoring; that's sensible.
I'll quit ranting now, but as a person who has had suicidal inclinations in the past, I feel horribly slighted when people laugh it off as attention whoring or being a selfish, cowardly asshole.
