David Spade donates $100,000 to National Alliance on Mental Illness one week after sister-in-law Kate Spade's suicide

Just over a week after Kate Spade took her own life, her family is taking steps to prevent the same outcome for others.

Kate's brother-in-law, comedian David Spade, is making a $100,000 donation to the National Alliance on Mental Illness. “More people suffer from mental health issues than we may realize, but no one should ever feel ashamed to reach out for support,” David said in a statement to People.

David also encouraged those suffering to reach out via the National Suicide Prevention Hotline (800-273-8255) or nami.org.

David's older brother, Andy Spade, wed Kate more than two decades ago. After news broke of her June 5 death, David shared a few personal photos with his sister-in-law, including an undated family Christmas snapshot.

"Fuzzy picture but i love it. Kate and I during Christmas family photos," he wrote. "We had so much fun that day. She was so sharp and quick on her feet. She could make me laugh so hard. I still cant believe it. It's a rough world out there people, try to hang on."

The "Saturday Night Live" alum performed a scheduled stand-up comedy set in Brea, California a few days after the tragic development, acknowledging the events to the audience: "Thank you for coming. It was a rough week, but I didn't want to cancel and I appreciate you all coming out here," he said, according to E! News, adding, "And if my jokes don't work then I get sort of a free pass."

After Kate's death, her husband confirmed that the couple had been separated for at least 10 months and that Kate was in treatment for depression and anxiety.

"We were in touch with her the night before and she sounded happy," Andy said in a statement. "There was no indication and no warning that she would do this. It was a complete shock. And it clearly wasn't her. There were personal demons she was battling."
