Negative thoughts are unwanted ideas or beliefs that can lead to feelings of sadness, anxiety, or frustration. They often focus on self-doubt, failure, or pessimism about the future. These thoughts can arise from various sources, including past experiences, stress, or even biological factors. When negative thoughts become frequent, they can affect a person's mental health and overall well-being. Techniques such as cognitive-behavioral therapy (CBT) can help individuals recognize and challenge these thoughts, promoting a more positive mindset. Addressing negative thinking patterns is essential for improving emotional resilience and quality of life.
