i think it is selfish in a lot of cases. i have very little family (mom, sister, and niece), and they are the reason i havent commited suicide for many years. while i feel like i cant cope with my own pain, i would never relieve my own by causing tremendous amounts to the only people i love. whether or not they love me in like amounts doesnt matter.
years back, my former bosses wife hung herself from the cieling fan in their living room. he was the most cold hearted man ive ever met, and he was never the same afterwards. he was dead inside. even the coldest of people have the ability to blame themselves for the death of a loved one
believing that your own death, especially a suicide, wouldnt hurt the ones around you is the very definition of selfish. theres a huge difference in feeling alone, and being alone. i spent a month without a home, and that kind of true lonliness made me yearn for the days when i would sit in my room, and sulk in the fact that no one understood me.
then again, some people truly have no one....
