After offering a brief statement on her mother Nancy Reagan's death on Sunday, Patti Davis is responding to the "haters" who described the original message as "terse".
"To the people who called my short piece on my website 'terse' perhaps you haven't experience how overwhelming it is to lose a parent. It's also overwhelming to go through that in the public eye," Davis, 63, wrote on Facebook on Monday. "I felt it appropriate to thank all of the people who had sent their condolences and that's what I did.
"That was the purpose of that post, written on the day of my mother's passing. It's shameful that people would find fault with that, but then 'the haters are going to hate.' Please try to stifle your criticism at this time. It's very inappropriate."
Davis' original message referred to the 94-year-old former first lady's death as "expected", adding "my mother had been in poor health for quite a while, and recently had gotten markedly worse, so this wasn't a surprise."

Reagan's health had been declining over the past few years, as she suffered a broken pelvis in 2008 and suffered broken ribs in 2012 after a fall in her Los Angeles home.
Despite some dissent, Davis did add in the message on her website that she took comfort in the "attention and prayers of people I will probably never meet."
After Reagan's death, a spokesperson said in a statement, obtained by PEOPLE, that their would be an opportunity for the public to pay their respects at the Ronald Reagan Presidential Library in Simi Valley, California, before the family laid her to rest.
