David Spade is honoring his sister-in-law and designer Kate Spade after her suicide at the age of 55.
PEOPLE exclusively confirms the actor and comedian, 53, has made a $100,000 donation to the National Alliance on Mental Illness (NAMI).
“More people suffer from mental health issues than we may realize but no one should ever feel ashamed to reach out for support,” Spade says.
“If you or anyone you know is in need of help or guidance please contact the national suicide prevention hotline at 800-273-8255 or go to namiccns.org to learn more and help those who may be in need,” he adds.
NAMI is the nation’s largest grassroots mental health organization dedicated to building better lives for the millions affected by mental illness through educational programs and support groups.
