Some people experience depression only once in their whole life, and other people experience many bouts of depression. Sometimes people who are depressed can't do even the simplest daily activities - like getting out of bed or getting dressed. Other people go through the motions, but it's obvious they aren't acting or thinking like their normal selves. Because it's in the brain, depression can make people think their unhappy feelings are their own fault. So sometimes depressed teenagers think they deserve to feel awful.
Depression can make people exaggerate bad feelings about themselves.
Sometimes depression makes teenagers think they are fat and ugly. This is another reason why it's important to get treatment for depression before it leads to other trouble. Research studies show that depression can run in families. Depression can begin suddenly for no apparent reason. Other times, depression can be associated with a life situation or stress.
