Quote:
Psychologically speaking, suicide is a cry for attention.
That's a fairly inaccurate blanket statement.
I don't have time to go into an in-depth explanation, so I'll just blurt out some facts.
Initially, humans do not choose to exist. They are brought into this world against their will. Then we impress upon them that they have an obligation to keep existing, that it is wrong for them to purposefully stop living.
People strive to be happy. (This is also where we see large inconsistencies in Maslow's hierarchy). This may apply to animals as well but I'm not aware of any cases in which an animal forfeits their life due to an inability to achieve a happy life.
Anyway, there must be an incentive to keep living. Simply being able to survive is not enough for a person to WANT to survive. This means that to some extent, expectations must be fulfilled on that person's part.
In other words, if you only find suffering in life, why do you want to live? Answer: you don't. This is why people kill themselves.
Failed suicide attempts -may- be a cry for attention. That's not to say that a cry for attention is just the person being a whiny brat. It means that person is not sufficiently happy to want to keep living, and they need some external influence to change that, just like if you're hungry and you can't get food for yourself, you let people know "I'm hungry!".
Actual suicides are never a cry for attention. The person has accepted that they will not get what they desire from life and there really is no point in living a life where you feel that way all the time. It's equivalent to someone starving to death.
In other words, the person doesn't need "attention". Attention won't fill a hungry stomach, and it likewise won't in and of itself make a person's life suddenly have meaning and be empty of misery. It's simply a prerequisite. If you're hungry and can't get food, you need someone to pay you attention and feed you. If you want to die, you need someone to pay attention to you and help you through it.
