There are many different causes of depression but common causes include genetics (if you have it in your family), medicines, death (maybe of a loved one?) and abuse. If you think you might be suffering from depression, it’s important to talk to someone about it. There is medicine that you can get from talking to your doctor if they think it is really bad 🙁
Causes can range from genetics, trauma, hormones, and drug use.
Some scientists believe it’s to do with a chemical imbalance in the brain. However, the evidence for this is thin.
As Maggie said, if symptoms get bad people should seek help.
