The comedy superstar passed away after hanging himself at his home in Marin County, California, at age 63.
Zelda has openly mourned her father on social media websites, and now her friend Frances Bean has offered the grieving 25-year-old a shoulder to cry on.
Frances, whose Nirvana rocker dad Cobain died in 1994 when she was just 20 months old, writes on Twitter.com, "You have such an incredibly beautiful soul. I love you but you already knew that. Wherever, whenever u need me I'll be there (sic)."
Meanwhile, Zelda is taking a break from social media after she was sent hurtful messages about the death of her father.
She wrote on Instagram.com on Tuesday, "I will be leaving this account for a bit while I heal and decide if I'll be deleting it or not. In this difficult time, please try to be respectful of the accounts of myself, my family and my friends.
"Mining our accounts for photos of dad, or judging me on the number of them is cruel and unnecessary. There are a couple throughout, but the real private moments I shared with him were precious, quiet, and believe it or not, not full of photos or 'selfies'.
"I shared him with a world where everyone was taking their photo with him, but I was lucky enough to spend time with him without cameras, too. That was more than enough, and I'm grateful for what little time I had.
"My favorite photos of family are framed in my house, not posted on social media, and they'll remain there. They would've wound up on the news or blogs then, and they certainly would now. That's not what I want for our memories together. Thank you for your respect and understanding in this difficult time. Goodbye."
