I came to the conclusion that I'm alive against my will and never consented to exist to begin with (as with all living organisms that came to be) and that is the philosophical component. Then for the emotional and self interest component, it would be that it isn't fair nor ethical to put others' interests before mine, and then be trapped in existence for an indefinite amount of time (decades or so) just for the sake of keeping others' happy and comfortable. My interests and suffering against my will are just as (if not more) important than appealing to their morals and ethics. When I reach that point in time and circumstances are right, I will follow through and fuck having to suffer unnecessarily just so others' can feel comfort and not be upset, that is very unfair and unethical. I finally believe that one's (ultimate) bodily autonomy and such comes first, as long as they don't actively physically harm others' liberties (and I don't consider 'feelings hurt' to be real harm - because by that logic, no one should ever sever abusive relationships, quit abusive work contracts, unsubscribe from predatory business practices, etc., to which most people would find absurd).
