Rebecca Brown had an idea for a fun photo project.  She started taking a selfie a day for a period of 6 years.  Sure, that might sound silly to some people.  But it's more than just a collection of smiles.  It shows her as she deals with an impulse control disorder called trichotillomania. 

Yeah, I didn't know what that was either.

It's a condition that causes her to pull the hair out of her head when she feels anxious.

Despite her struggles, Rebecca generally has a smile and she seems to have hope. 

I hope you enjoy this video as much as I did.
