You must be joking
Obviously there are lots of men with depression, even if it is more easily diagnosed in women. As a depressed person you should learn one basic truth: you can't talk about it with anyone.
The simple reason why most people don't understand is IGNORANCE. And no, you CAN'T snap out of it.
So don't hesitate to lie to those who couldn't understand. Say you didn't sleep, say you have headache, say whatevere but don't say depression. This is not out of shame, it is survival in a world where stigma is a fact.

The best of luck
