Me: I have depression

People: 

It's just a phase.
Or
These days teenagers just like to make a hype about things, depression is just another word for sadness.
Or
But you haven't had a trauma and you are also from a well-off family then how could you have depression.

°°°°°°°°°°°°

People need to understand that depression is not a boyband with whom we are obsessed with but will eventually get over.

And depression is not definitely sadness and if it is then I'm sad from the last one week for no reason.

Lastly, depression doesn't only happen to those who have gone through a trauma or have a broken family. Surely, these things can be one of the reasons for depression.
Depression is not a human who will judge people on the basis of there race, colour, gender or position in society. It can happen to anybody and at any age.
