Why do teenagers tend to be more depressed than they were as kids?

Some teens get depressed when something dramatic comes up or when there is a problem.

the above answer is kinda right AND wrong tbh. Teens can get just as depressed as adults can, for the same reasons. You can be born with a dispossition, or could have been hereditry. but either way it is a mental illness that doesnt always come from one particular event, YES teens can have depression.
