Jealousy stems from a fear of losing something valuable, like a relationship, and a lack of self-worth. It is often rooted in past rejection or broken trust from an early age. To overcome jealousy, one must identify the triggers, build self-confidence through positive self-talk and comparing oneself less to others, learn to trust by giving others the benefit of the doubt and addressing relationship needs openly, and help others through volunteer work to shift the focus away from oneself. With support, self-examination, willingness to change, and hard work, overcoming jealousy is possible.
