People don't care about themselves because they have been forced to believe that it's wrong when you do, that it's selfish and all the rest.

It is that which drives the person towards the suicide in the first place, because it instills a feeling of worthlessness, etc. and that you are not worth being cared about.

Even though others care about you, only you can care about yourself in a way that is sufficient enough for you to be totally satisfied.

It's like taking a thirsty man to a puddle of water, but you can't make him drink, he must want to drink, also you can't drink for him. He has to want to drink for himself otherwise he will suffer thirst and eventually die of thirst. But, when the man is thirsty, and he bends down to drink, people then can't turn around and call him selfish for using the water.

People will always accuse. If he drinks, they call him selfish because he uses the water, if he doesn't drink and dies, they call him selfish because he has removed his presence from them. With that in mind then, he is the only one who can do something for himself because the others just stand and accuse at best.
