-Teach yourself to be more aware of your thoughts, so that you recognize negative thinking as it arises.
-Start challenging each negative thought. Feel free to argue with yourself when any specific self criticizing thought arises.
-Tell yourself that thoughts are not true. This way we start taking negative thoughts less seriously and they have less of an effect on us.
-Learn a meditation technique like mindful meditation to enable you to better recognize the types of thoughts you have throughout the day.
-Journaling is another good practice that helps a person deal with repetitive, negative thoughts. Seeing those thoughts in writing makes them less scary and easier to deal with.
-Spend more time doing positive things that enrich your spirit and help you focus on the good in life.
-Learn how to practice gratitude in your daily life. Keeping a gratitude journal is a good way to begin doing that.
-Be kind to yourself always. This means setting realistic goals, being gentle with yourself when things don’t work out, and talking in a loving way to yourself.
Banish it for good: When this type of thinking regularly comes up about something more permanent, like your body image or your marriage, try this: Write down your negative thought, crumple up the paper, and throw it away. In a study at Ohio State University, people who wrote down negative things about their bodies and then tossed the notes had a more positive self-image later compared with those who kept the papers with them. "They physically discarded the thoughts, but it was as if they'd mentally discarded them as well," says Richard Petty, the study's coauthor and a psychology professor at the university.
For example, they may say, “I’m a loser” in a situation where they failed at a specific task. When someone else’s behavior rubs a person the wrong way, they may attach an unhealthy label to him, such as “He’s a real jerk.” Mislabeling involves describing an event with language that is highly colored and emotionally loaded. For example, instead of saying someone drops her children off at daycare every day, a person who is mislabeling might say that “she abandons her children to strangers.”
