It happens.

Actually the other day I was having a deep conversation with my coworkers and all of them admitted going through really dark times. They seem to have their sh*t together and leading a happy productive life. Some of which brought up serious issues like suicidal thoughts even if they covered it up with humor. I thought to myself, wow, thought I was the only one. Discussing mental health is a bit of a taboo over here.

I’ve had major depressive disorder since I was a kid. It’s a hand full of pills twice daily and a conscious effort to not be depressed for no apparent reason.

I didn't even know it was Depression for the longest time. And I guess there have been many reasons.

Epilepsy is my reason for being defeated. But that is just for 3 or 5 days

No, I get depressed because of the chemical imbalance in my brain

The operative word is, apparent.
I'm sure I could find a reason.

Always reasons never want to think about them

I suffer from clinical depression. A cause, but not technically a reason.

I used to, then I read something about sugar causing depression in some people. So, I quit eating sugar and it stopped happening.

In some ways I'm lucky, I was never short on reasons, and that actually gave me a direction

It seems so, but I believe there are reasons.
Could be simply low dopamine or serotonin levels.

All the time - it's normal life basically.

Yes but if I dig deeper usually I can find a reason

No
There's always a reason

It’s for reasons I already know

All the time. I have triggers too.

Very rarely.

Very rarely.

Yes. I hate it.

I have lots to be depressed about but it will just hit me at times. Sorry you are feeling this way.
