Writing for Motto, Bell noted how depression is not sadness.

Its not having a bad day and needing a hug.

It gave me a complete and utter sense of isolation and loneliness.

Its debilitation was all-consuming, and it shut down my mental circuit board.

I felt worthless, like I had nothing to offer, like I was a failure.

Its a knee-jerk reaction to judge people when theyre vulnerable, wrote Bell.

But theres nothing weak about struggling with mental illness.

Youre just having a harder time living in your brain than other people.

And I dont want you to feel alone.
