Rebuilding your self-esteem after being in a relationship with a narcissist can be difficult, but it is essential for your emotional health and well-being. Engaging in self-care activities that make you feel good about yourself and surrounding yourself with positive, supportive people can help you on the path to recovery. Additionally, focusing on your needs and prioritizing your well-being is important to start the healing process. Finally, seeking support from friends, family, or a therapist can be beneficial in building up your self-esteem and helping you move forward.
