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. People can get seriously depressed after something like a divorce in the family, major financial problems, someone you love dying, a messed-up home life, or breaking up with a boyfriend or girlfriend, failing classes, being teased or rejected. Don't forget - depression is physical. Once a person's brain chemicals have shifted into depression, it doesn't matter why the depression started. That person needs help.
