First things first: make sure you speak to a doctor if you are feeling down.
Your GP can talk to you about your options, and give you a ‘mental health plan’. They can also run tests, make diagnoses or prescribe particular treatments, such as medication, if needed.
Figuring out the cause of depression is important because it determines prevention and treatment.
Depression can be a symptom of other health or medical issues, for example, if you had a vitamin B12 deficiency, you would feel low or fatigued.
It’s important to treat the cause, rather than just the symptoms. That’s why you should talk to your GP.
