Anticipation
Anticipation is a state of expectation or excitement about an upcoming event or situation. It is a state of suspense and expectancy. For example, when you know an old friend is going to drop by you probably are in a state of anticipation while waiting for them - you are excited, maybe a little nervous, and filled with expectations about their visit.
People think they can destress and regulate their emotions by using only their minds.
