WHAT THING MAKE ME HAPPY AND SAD?

It makes me happy the positive people, when I am happy, I smile every moment, but the people who are always angry make me sad I feel angry too. When I'm sad, I usually eat. When I feel stressed it's horrible, when the people don't listen to me, when I don't understand things, when the people are chatting more than normal I feel stressed and then, I talk to a friend, watch TV, sometimes I read a book... These things make me feel better.
