How long ago was that and you're still crying? Your parents didn't take personal responsibility and purchase adequate life insurance and set up who takes care of the kids if the unthinkable happens. You've continued that cycle of not taking personal responsibility with your own life by embracing liberalism, a political philosophy that hates personal responsibility.
My parents always had a will and insurance. My wife and I have done the same and kept it all updated. We've had to change our children's contingency caretakers several times as my parents situation changed, my wife's mom, then two of my sisters, in turn, then back to my wife's mom, which was touch-n-go until her son died of a long illness. He, by the way, paid for all of his hospitalization, well over a million dollars, from his inheritance from his father's will and life insurance. We elected to give our share all to him, and my sister-in-law did the same. When he died it was all gone except less than $100k, and after taxes our share was less than $20k. Finally now our son is 19 and very responsible and he would be the guardian for our daughter, and my wife's mom the secondary as well as executor until they are both college graduates.
Don't expect me to defend you. Defend yourself.
