Since they are opposites, I would use "between".
Student or Learner
I was about to use "between serenity and turmoil", meaning someone who is facing both conditions, but now I am hesitating about the the best of the following options:
between serenity and turmoil
among serenity and turmoil (I believe this one is not an option)
amid serenity and turmoil
amidst serenity and turmoil
Any help would be appreciated.
Thank you so much, Mike.
But, just to clarify, imagine if they were not opposites, for instance "peace and tranquility". In this case, which one would you choose?
You can't choose between peace and tranquility.
