Yesterday was World Mental Health day, a day to raise awareness about mental health awareness and mobilize efforts in support of mental health.

Zelda Williams did just that. The daughter of the late Robin Williams used Twitter to inspire and encourage people to seek help.

After her father's tragic suicide on August 11, Zelda is trying to end the "stigma" attached to mental illness.
