As the eldest sibling, I am usually responsible for deciding when,or even if,my younger siblings can go on vacation. This time, I do not want to go on the trip, which consists only of me, my siblings, and some close friends. I am completely drained from university and want to spend my days off at home. However, my siblings have already planned everything; since they cannot go without me, they are trying to persuade me to change my mind. I am worried that my exhausted mood will ruin the experience for everyone. When I spoke to my parents about it, they simply said I was being indecisive. I have been crying over this, the guilt is unbearable.What should I do?
