Emotional Release

When trying to practice Emotional Release, I find sometimes I am unsure how to identify “the” one emotion I am feeling, as at times I feel it could one of many. I may feel like there is Anger, Jealousy, and for example Rejection happening at the same time. How do I choose which “one” to identify? Is there an Emotional pecking order as which ones may be a more important to release than other?
