A psychologist is someone who helps people understand their feelings and thoughts. They are kind of like a doctor for your brain! They talk to people and ask questions to help figure out why they might be feeling sad or worried, and then they give advice on how to feel better. They can also help people understand why they act the way they do and how to change it if they don't like their behavior. Sometimes people go to a psychologist if they have been through a tough experience, like losing a loved one or going through a divorce. Psychiatrists are like psychologists, but they can also give medicine to help people feel better. Think of them as doctors for your brain and emotions.
