It can have many reasons why people would commit suicide, and to make it easier i will split this up in 2 main cathgories.
1) Taking your live because you really want to.
2) Taking your live because you want to prove something.
Now the person who tries to take his own live because he wants to doesnt care about other people. He doesnt warn anyone, he doesnt show it to anyone and quite often doesnt even leave a goodbye message. This person will take her own live and you will not even notice that the person wants to until she does it.
There is no way to help this person as you will not notice before the suicide, and even if you stop the person whilst she attempts to commit suicide that wont help. This person will always look at suicide like the only way out and it will come back to her even 30 years after the first attempt.
The person who makes suicide because she wants to prove something doesnt really want to commit suicide. This person will gradually come into the phase and you will notice that if you are close enough. This kind of person needs help and she can be helped. Even if the person attempts to commit suicide she doesnt really mean it (the first time, maximum the second time) but if it comes to the point of attempting again then its most probably serious. Note that this person will need help all her live, and will always need someone strong at her side to help her all the time. Even if you might think this person is "cured" it can happen again that the person tries to commit suicide many years later.
Note to anyone who wants to attempt suicide:
Now many people say suicide is selfish but i wont go into that. The only thing i want to say is that if you do it, you obviously take your own live and noone elses so you should try not to harm people too much with it. Dont just jump under a car infront of a school and dont shoot yourself in the face because that just harms people close to you and people who love you. Even if you want to commit suicide, do you really want your mother to identify the corpse of your totaly splattered face? Do you want to give people a trauma that might stay all theyr live? If you want to commit suicide i know that i cant stop you so at least try to make it the less harmful for other then it can get.
"I decided that this live makes no sense anymore and that i cannot live with this pain, im sorry" - Commits suicide, noone ever suspected that the person would do that and they will always ask themselves why the person did.
Writes a text to the boyfriend "I think this is too much for me in my live, i am going to kill myself, i love you" - Boyfriend runs to girlfriend and stops her form doing it, then supports her on the way to the cure. This person didnt really want to die, but was so desperate that it was the only way to get someones attention on her problems.
Similarly, one who is considering the act should consider others. Other than in the instance of proving a point, it should be done discreetly and not in an overly dramatic fashion so as not to cause others undue or excess pain. As someone who has considered it many times in the past, I have thought it through very thoroughly, and while some may consider suicidal thoughts a sign of depression I would like to note that it has always cheered me up in my moments of despair as it reminds me of my impermanence and that my troubles will all be over one day. It has allowed me to cope. I speak, mind you, not only as the "melodramatic self-piteous emo goth freak" but also as someone who has been on the other end.
Most notably, one should consider just how irrevocable the act is.
2. A friend of the family took a bottle of pills and commited suicide, in a moment of regret she left an appology.
3. Suicide, like many other things, is not ours to judge as right or wrong - but the decision should be weighed heavily.
p.s. saying to god, "you can't fire me, I quit!" lol - that was a good one.
---Never ignore somebody if they start to talk about ending their life. Most of the time it is NOT for attention. Most of the time it is a cry for help. They are asking for somebody to show that they care. They aren't doing it to be called a poser or stupid or an attention-seeker or any other shit like that. They're saying it because they actually DO want to end it...they do actually feel the need to die. And if you just ignore them, how are you going to feel when you find out that they're dead? Think about it...just try to help the individual as much as you can.
---Suicide is NOT a selfish act. You all say that they're leaving their loved ones behind and hurting them, but that really only makes you selfish. How can you expect this person to continue living through all the pain that their life is giving them? To go through the feeling of being invisible, like they have no one to confide in? To go through feeling like everybody that once loved them has now abandoned them? And to go through feeling that everyday the walls are closing in on them and that everyday they are sinking further and further into despair? Into loneliness and heartache? How on earth can you expect someone to live with that all the time, just to keep everybody else happy? It's not like it's their duty to make everyone happy. So stop being selfish yourself and think of the individual for once.
---Don't think that suicidal people don't care about you. One of the common reasons for suicide is that the individual doesn't want to hurt their loved ones anymore. And though they know that suicide may hurt their loved ones, it stops the individual from ever hurting them again. Better once than a million more times. And deep down inside, the individual probably does know that people do care, but they just can't believe that when they're feeling so down and out. It's just hard to think that people care about you when you feel that they never seem to show it and they never seem to be there when you need them most.
---If you are someone who believes in fate and God and you believe that everybody has a particular time to die made for them, then you should also believe, as sad and horrible as it may be, that suicide is meant to happen. Perhaps the individual is actually MEANT to die at this time and it just so happens that suicide is the way they die?
I really don't know...I'm just putting down my opinion. I hope it helps at least one person out there.
---This definition wasn't intended to encourage people to commit suicide, I am merely hoping that it will help everybody else to understand a bit more about suicide and why people commit it.
