Tell your parents what you mentioned in the note, and ask them to arrange an appointment with your pediatrician. The doctor will want to rule out any physical cause for your symptoms and, if you're OK from a medical standpoint, can guide your parents about how to arrange an evaluation with a mental health professional. If for some reason you are not able to approach your parents by yourself, perhaps you can confide in a trusted relative or family friend, or speak with a teacher or guidance counselor at school.

It's not as easy as it sounds. You cant just go up to them and tell your parents. its hard. They might think you are joking or something. It's really not easy, so dont assume it all ok when you tell them.
