Does depression need a reason/cause?

Not always. Sometimes you find it hard to tell why you feel depressed. You might get depressed without a known reason or different situations might lead to depression.

No, absolutely not. Depression can just happen, and leaving us with no control over it. Sometimes we have reasons, sometimes we dont.

not always, sometimes depression is just there and you dont know the reason/ cause. usually the reason is hidden and you may have to dig a little deeper to find it.

No, depression can be caused by a mere imbalance of chemicals in your brain. It is not always caused by a life changing event or trauma.

It doesn't. Depression is a chemical imbalance in the brain. While it's true that some groups of people (women, chronically ill, etc) could be more receptive for depression, depression doesn't look at age, color, wealth etc. It's just there. Anyone can get it, just like the flu. But because it's something mental instead of physical, that is hard to understand for some people. That's why it's important to address the current stigma on depression. Just because someone is young and has a roof above their head, doesn't mean they can't be unhappy. You can have it all, and still have depression.
