On selflessness

From a reader:

As a constant, I am aware of the fact that nobody means much to me as aside from what they directly provide. That actually doesn't sound terrible: while everybody tries to side-step the matter and down on the word "selfish," to be "selfish" is healthy. Normal people get a selfish pleasure out of the well being of those whom they care for. "Selfish" does not have to mean at the expense of others, only that you are doing it for yourself. If you feel good donating to charity, you are going to do it because you enjoy that. It is only when donating to charity makes you unhappy and you perform it as a perceived obligation that it is truly selfless (although, even then, you are probably donating for the personal reward of an afterlife, or for the personal reward of social approval). Can you imagine an atheist schizoid with better use of his money chucking it away instead? Where's the motivation?                                                                                 
    
But I don't feel bad when those presumably close to me suffer. I only choose to extend a facade of "are you alright?" because I fear that they will catch onto such and stop contributing to whatever it is that I keep them around for. How can I expect sympathy for my suffering or understanding when the root of my condition stems from the idea that I will never be able to reciprocate affection? What masochist is willing to love and attend to a brick wall? Perhaps one of delusion, but then, he doesn't understand, and can't even begin to entertain my honesty. So what can I say, except "I am sorry that this is how I am"? Even when I apologize for it, it is less because I feel bad that I hurt them, and more a wave of self-pity when I want something to preserve. I'm sorry. I can't help it.
