She went on to add a number of helpline numbers, adding: "A thread of suicide prevention resources I have mostly posted before. Please add any others you know of that may be helpful to others below too, so they can find them. I don't ask for much, but if I may, be gentle to your hearts today. I know I'm trying."
Zak previously opened up about his mental health struggles after Robin's death in an appearance on The Genius Life podcast admitting he battled his own demons in the aftermath of the tragedy. He said: "I was heavily drinking to manage my mental health where it created very harmful issues. For me personally, I was having health issues. I was experiencing some psychosis and when I spoke with a psychiatrist I was diagnosed with Post Traumatic Stress Disorder. I was self-medicating through the trauma using alcohol."
Zak was able to heal using a 12-step programme and group therapy and credits becoming a mental health advocate with helping him move on with his life.
He added: "I was just sick and tired of trying to treat myself using harmful means."
