"So, it's that time of year again. I will be taking another break off social media. For those who always ask why, it's so people can memorialize Dad on the anniversary of his death however they wish without me having to feel bombarded by it, or pressured by the expectation put on myself or my family to publicly acknowledge or join in doing so," she wrote.
"I will always be so grateful for all the love the world had and continues to have for dad, but for obvious reasons, it's sometimes harder to be the sort of surviving public vessel for receiving those sentiments, and one often expected to somehow flawlessly express them back.
"Thus, I’ll be excusing myself for a bit. Hearts just need little breaks sometimes!"
Williams went on to say she would be remembering her father privately. "Obviously the world will keep on spinning. This is hardly an important issue, my main point being you should continue to remember Dad however you want! I'll just be doing so privately. And if you'd like to celebrate his life by celebrating causes he loved, you need only google, and you’ll find wonderful charities like the @ReeveFoundation, @CAFoundation and many more.
