my mom apologized for being sick and not able to get out of bed. and so right now, i really don't know what to feel but can i apologize for dying too early?

being the eldest daughter i am, i am afraid of the thought of losing my mom and dad due to any sort of sickness. not that i don't believe in God's wills, but i really wish they'd be there for my graduation, my marriage, my life as i grow older - if i even get there. anyhow, my younger siblings wouldn't be able to survive without my parents. both of them are sick now, for quite a not so old and still not so young age, they're already sick. being sick is is torturing for some. i can't bear seeing my parents suffer from those anymore. i'd rather contain all of their sickness and never reach 25;
