How long should one HAVE to endure such pain? Why is it such a big deal to let go?

For whom and what does one live for when it is quite obvious that there is no desire to go on (and hasn't been for years and years)?

And why is it that "guilt" over what a "loved one" would feel (and the resulting embarrassment they may feel) always be the reason to continue going on day after day after miserable effin' day?

Why does it become so important that their feelings are always considered first - always considered the only ones who truly suffered after a loss? What about our pain? Why are people considered "losers" if their choice is not to go on?

Why is "the physical" the only measure of discomfort our society is willing to accept as a "good enough" reason to let go?

Why is it not acceptable to even say "I've had enough?"
