Wow, it's interesting to see everyones opinions on this. I may not agree with some of what was said, but I do see where everyone is coming from.
I had a friend, who literally was so messed up, that I truly thought that suicide was the only thing in this world that would make him happy. That being said, I never told him that, because clearly the selfish part of me wanted to keep him around always. If he had actually gone through with it, I would never consider him a coward. I thought he was the strongest person in the world for waking up every morning hating himself, and his life, but trying to put on a brave face for the rest of the world. There was no "getting over it" for him. When you have that many issues, no amount of drugs, (aside from maybe a relaxant for elephants, that wouldn't solve anything, just make you not feel a single thing for the rest of your life) can make things better.
No matter the reasoning, some people are born a little different than most. Between the constant reminder that they're different by peers/bullies/parents/teachers/etc, and the lonliness and hopelessness; it's hard to see the point in living. Suicide is probably the least selfish action, when that person truly cannot be cured. Asking them to stick around... That's the only selfish part. How do you ask/guilt someone who can't stand being in their own body/mind, to stay in this world where there is clearly nothing for them here, to stay living solely because YOU would miss them? If someone is really thinking about suicide, and it's not just a spur of the moment thing... Think about all the thoughts they have to endure every day:
"How am I going to do it?" - They literally spend hours and hours thinking about how they're going to end their own life. I don't care who you are, that isn't a walk in the park to think about.
"Who am I going to affect?" - In some regard, some of you guys are right by saying they don't think of the people they're leaving behind. It's not that they're not thinking about how you'll feel, it's they feel like no one would miss them, if they were gone. If someone felt like they had tons of people who cared for them and loved them, and felt wanted and secure... Why would they want to end their life in the first place? (Minus the few crazy people who just do it for some form of attention.) Usually, it's the lonely feelings that overwhelm them, as to why they want to just slip away...
"What's it like to die?"
"Will things be better for me, if I go for the big sleep? Or is there actually a God, and will I burn in Hell for killing myself? If by chance there is Heaven and Hell, will it be worse than living here?"
The list goes on and on!
Suicide for most people isn't an easy solution. I don't think you're giving the victims enough credit. Being over-powered by your own thoughts... That's a scary situation. Being on countless drugs so you're a living zombie, just so you can pretend you're thinking normal thoughts like everyone else... That's a horrible life to live. Leaving everything YOU care about, regardless of if you feel they care back... Can't be an easy choice.

All that being said, I really don't think that ALL the cases of suicide were to the extreme explained up there. For most people, depression starts with something small, that snowballs. There is no way to just "get over it", if you're actually depressed. You can't just wake up one morning no longer upset by the things that depressed you the day before. With help, and the proper guidance, though, it can be over-come before it gets to the point of no return. But its in times of depression when people need the most help from others, even if they're too stubborn to admit it. When you have a strong friend/family base, it's easy to get the help you so desperately need... But put yourself in someones shoes who has no one. Who is faced everyday with just people who look down on them, or tease them, or bully them, or make their life harder than it needs to be. When you are in such a low spot, and you need someone to be that light at the end of the tunnel, but no one comes... don't expect them to make it out of the tunnel.
