"It's a family obligation" and "I have to sacrifice myself to the volcano god" are almost phrasal homonyms. They sound identical, right?
My mother is mobility impaired. So I care for her. I have two little ones myself. I feel bad, but I just shut down that evening and the next day or two. I'm mentally numb and physically stunned.
And these religious events occur three times a year. (Turkey Day is a religious holiday among most of my relatives).
There's nothing for it. I think these events are part of the reason why I have withdrawn from much of society. Even fucking is losing appeal because social conventions are attached.
I feel your pain.
