I wanted to ask similar question. I do not love my family anymore. We usually are very emotional about death and family. Emotions stop us from doing what is right or might stop us. Let us consider:
I didn't choose my family or my birth. They love me because I am their son or grandson, not because who I am really (consciousness, soul, spirit). Nobody choose to be here. There is nothing here to do or to achieve so death won't matter in great scheme of things. I love my family and empathies with them. They make me angry because they keep me here. and non of that arguments matter. There is great fear of retribution after death. "you hurt so many people by dying"
For me earth and body is a prison and life is death sentence, having hopes about life is Stockholm syndrome, because how the fuck could you enjoy that life. 9-5 for 40 years? health problems? Loneliness, boredom, depression and emotions. I don't want those. One could leave a note saying: "I loved you all but I couldn't enjoy my life "
There is no point in being martyr here. The evolution created many of those. I don't like system and system doesn't like me so why would I help It. I rather save myself.
Also If your parents couldn't help you in any way why would you help them. Truth is they love us like objects because mother nature said so. I try to be human but They shouldn't held us captive. I have a will to die and I have a right to. If I said It to my mother I would be sent to mental hospital for sure, or at least psychotherapist who helped nobody ever but It is easier to tell somebody to go to one than repair what cannot be repaired. We can only do stuff they expect from us, stuff that just repeat the cycle of samsara. Breed, find job, take care of me. They love us but we keep them from seeing us because we know they would be afraid and possibly disappointed in seeing how bad we do in this world. We kept secret from them so long It ate us alive and when there was nothing left we left our bodies behind with short suicide note. Parents might be cause of our suffering, truth which we fear, their neglect, or harm or simple mistake. We love them because they are our creators, our gods.
We were dependent on them for such long time.
They see themselves in us. We are their investment of time love and genes. We are the last chain of unbroken tradition of mindless reproduction, everybody in your family line was birth, lived, had sex, and died. For billions of years before you. Many have not and died without kids. Ate by predators or killed by disease. You might be one of them, killed by depression, neglect, bullying, chronic pain. but in this predicament the last strike came from your own hand. You were the one to turn the sword against yourself and said: "enough is enough". And your parents will be traumatized. "so young he/she died" they will say while I feel burden of memories knowledge and experience of many lifetimes. "he/she had such a bright future ahead of her" they will say, while I was rotting in my house for many years, or was rejected by people. "we were so good to him/her, we spent so much money etc." I give this up to your judgment you see. The family will always have expectations even if they lie about It. You carry their genes and they want their genes to succeed. To spread and evolve, to continue to live, survive and reproduce in this blender.
I cannot stand morally on the issue as I see morals have no place here. There is no victors in that game. If you spare yourself you will suffer, If you go family will suffer, they will get over it though after some time. Nobody is irreplaceable, I am sorry to say that. If you manage to live happy life with your family: who will save all of the chickens and cows, that you all gonna feast on while happily existing? This world doesn't have any point to it. It is not a school of life. If you want to escape: do It. Just don't look back and don't return in here. Peace
