Negative affect is when you feel unhappy, sad, angry, or worried. It's like having a dark cloud over your head that makes you feel yucky. Sometimes negative affect is caused by things that happen to us, like when you fall down and scrape your knee. Other times, it's caused by things going on inside of us, like when we feel scared or lonely. It's important to talk to someone you trust, like a parent or teacher, when you're feeling this way so they can help you feel better. Remember, it's okay to feel negative sometimes, but it's important to learn how to cope with these feelings in a healthy way.
