I had suffer from severe deppression. To everybody it may seems normal but they describe it as "dramatic" said the person with no mental illness. IT'S NOT HOW IT SEEMS TO BE. I believe 90% of the persons which suffer from depression doesn't show how they really is, they may scare you harm you somehow, but most of the time they may seems happy for no reason. Depression doesn't harm you with any fever, rashes or physically. It kills you deeply; inside you till you found yourself useless, depression kill you with suicide or self harm, for me I never thought of suicide but I always thought of death. When peoples mentioned Cancer, my mind told me about myself because it's remind me of depression and anxiety. It's not how it seems to be, you just feels really bad and abnormal unlike the usual you. You'll feels really really tired, like you got no foods. You feels like you're hurt physically, but Nope it's mentally. I just want somebody to understand how It feels like to suffer from depression. It's hurt so much, you never wanna be judge! It's not your fault for crying all day to sleep or in the shower. Why can't somebody just understand that we never harm ourself or bring ourself to this ing situation? who would wanna be hurt this bad? But the inside yoh hurt so bad, something force you to do so. 

These are some symptoms if you wonder: 

-Tired/ lack of energy.

- hypersomnia or amnesia 

- feeling sad useless, crying, doing self harm.

- feels like only yourself can understand and no one care.

- feels like you're different and you can rule the world.

-hide yourself become an introvert
