A blackness that slowly creeps into your mind, one day at a time, little by little, slowly overshadowing everything that you do, until in the end the happy moments are unreachable, and nothing is left.
Of course, I could write a book on this question, but today I’ve tried to put it into one sentence for you.
Now, every depression is different. Can you try to put yours into one sentence? I’d love to read it.
The Healthy Path 
For me, the onset of an episode of depression is self-indulgent, almost decadent – like “I know I shouldn’t, but I’m gonna.”
I definitely relate to this. Good one.
Mine is so sneaky, like losing track of time. I look up and suddenly realize I have been thinking these terrible thoughts for days and days and didn’t even realize it. By the time I see that I am depressed and need to tell someone it is already over.
I agree with this as well. The thoughts have a way of taking over for some time without asking permission. Thank you!
