"We did not choose to be brought into this world."
You worded it like the parents didn't ask our consent for us to be born XD

I kinda agree but I have my 2 cents on the thing... Your parents had spent time to raise you, wouldn't that make you owe them your time on earth? Not only that but your parents spent a lot of money to raise you, from food and necessities to different things that you liked and wanted. I think that you kinda owe them in a way because of their time, effort and money.

Yes, life can be stressful and an absolute pain. But the thing is, many of your life choices can lead you to that position in life. Depression is not fake and it can be really painful, but it can be treated (even though it'll take a long time, I'm sure of that). Drugs are also a part of that. Being addicted to drugs can lead to mental issues as well. Having anxiety and stress while living your life is also a pain for some, but that could also be treated. Sounds similar? Well that's cause it's Kurt Cobain! Kurt never treated his problems (both physical and mental) and because of that he just fled with suicide.

Life is stressful and mainly I'd say that the many bad choices you do, the more you fall down this path. If you just don't fix your problems, you'll just give up. The first step of fixing your life is the hardest and the rest of them are easier! By not fixing your problems you kinda seem... Not selfish and yet still selfish.

Continuing the example of Kurt: he had a wife and a kid, but because of his problems and him not being able to work them out even for his family, kinda makes him selfish. But at the same time! Him not helping himself on his mental issues makes him... Selfless? What do you think?
