Q&A Emotions and Emunah

This week's question is: How do emotions work if you’ve built up emunah? If everything in the end is going to be okay, and you believe that everything Hashem does is for the good, how do emotions come into play? Are you supposed to suppress emotions? Will working on this definition of emunah lead to a deletion in negative emotions? Is that healthy? Or do emotions come into play in a different way?
