Adults usually have a very low, sad mood when they're suffering from depression. We teens act very irritable when we're depressed, but we don't know why we're irritable. We become lethargic and tired. Sometimes we eat a lot. We're also emotionally sensitive.
Clinical depression lasts for a long period of time.
You have to have to have the symptoms and signs of depression for at least two weeks in order for you to be diagnosed with clinical depression. The illness can last for months, sometimes years. Clinical depression is a low, unhappy, irritable mood and it s there every day, all the time. And it doesn t go away. Depression develops when your problems cause stress on the brain.
