We are happy at times, but sometimes we're sad or angry. Showing your (feel) is important. It is a mistake not (talk) with anyone while you're feeling sad, worried or nervous. If you keep bad feelings inside, they can even make you ill.
But if you talk with someone, . Your mum or dad, you'll usually begin to feel (well) than before. Now you're not all alone with your problems or worries. However, it doesn't mean your problems and (worry) will disappear magically (神奇地). But, at least, someone else (understand) what's the matter with you and can help you find ways of (solve) your problems.
Your mum and dad want to know it you have problems. They love you they want to know what's happening in your life. But if you don't want to talk with them, should you do? Find a believable (可信任的) teacher at school or a relative. Maybe that person can help you deal with your problems. Then you'll feel happy as before.
