We each come into this lifetime with at least one core issue to resolve. Different situations will continue to present themselves in different but repeat patterns until you have dealt with the core issues in your life.
A few examples of core issue are abandonment / victimization, demanding justice in all matters, living spiritually rather than materially. These are overarching issues that affect emotions completely. Many people find out about their core issues by learning to deal with their emotions. It is a gentle pathway that leads you into a deeper knowing of your core issues.
