A "bad friend" is someone who brings negativity into your life, whether through manipulative behavior, constant criticism, or a lack of support. These friendships can be emotionally draining and leave you questioning your self-worth. Recognizing the signs of a toxic friend is the first step in reclaiming your peace of mind. They might pretend to care while secretly undermining your achievements, or they could always be around when things are going well, but disappear during times of need. Letting go of these friendships is often difficult, but it's essential for personal growth and emotional well-being.
