We all assume we know what depression is, but do we really?

Depression is characterized as a mental condition characterized by feelings of severe despondency and dejection, typically also with feelings of inadequacy and guilt. Some signs of depression include lack of energy, lost of appetite, and sleep. Depression is a serious illness and depending on the person sometimes you don't even know if the person is depressed or not. A person can look happy on the outside, but in the inside feel hopeless, and sad.

Cara Delevingne just recently opened up about depression and how much it has affected her life. The celebrity said that her depression started at around eight years old, which is also around the same time that her mother was struggling with heroin. As she got older her depression worsened. By the time she was 16, Cara decided to deal with depression properly.

"I was suicidal", Cara Delevingne admitted in an interview with abc news. "I couldn't deal with it any more. I realized how lucky and privileged I was, but all I wanted to do was die. I felt so guilty because of that and hated myself because of that, and then it's a cycle. I didn't want to exist anymore. I wanted for each molecule of my body to disintegrate. I wanted to die."

Even with the struggles of growing up the celebrity described her mother as "incredible". "She always had so much love", "And I felt like when I was a kid I was kind of like her confidante. I really felt like I understood her and how she was feeling and why."

We all go through hardships in our lives. But, we have to remember that these hardships will only shape us to be better individuals. We may not know what happens in the homes of others, which is why we should never judge a book by it's cover, you never who has it worse than you do.
