We all experience life differently, but there are some common 'life situations' that make people feel a certain way.
According to some research, it's going to the dentist. The experience of sitting in the chair while the dentist is looking inside your mouth is terrifying for many people!
Problems with money and the future after education are top of the list. The future isn't always certain so people can feel anxious about what is next.
Sitting in a car in traffic when there's nothing to do is a common situation that causes this feeling. You can't read a book or watch TV if you're driving!
When you're feeling (e) tired, because, for example, you've got a lot of schoolwork or housework to do, you can try different things: breathing exercises and yoga can help. Being (f) calm can make you experience negative feelings, so make sure you get a lot of sleep!
