The term "negative feelings" refers to emotions or sentiments that are unpleasant, unhappy and discomforting. These can include feelings such as sadness, anger, frustration, disappointment, anxiety, fear, guilt, shame, embarrassment, resentment, jealousy, envy, loneliness, grief or any other emotion that brings about a sense of unease and discomfort. Negative feelings can arise from various sources such as personal experiences, relationships, situations, circumstances, events or even thoughts and beliefs. These emotions are natural responses to certain stimuli but when they become overwhelming or persistent, they may lead to negative consequences for an individual's physical, mental and emotional well-being.
