De Vries was ousted from his AlphaTauri seat by Red Bull advisor Helmut Marko on Tuesday just 10 grands prix into his rookie season, in which he failed to get on par with team-mate Yuki Tsunoda.
AlphaTauri called on Red Bull's third driver Ricciardo to take the Dutchman's place, the Australian joining the Faenza squad on loan after impressing his parent team during a Pirelli test at Silverstone.
De Vries has since kept radio silence, but on Wednesday, eight days after his dismissal, he took to social media with a statement in response to losing his F1 drive.
He thanked Red Bull and AlphaTauri for giving him a chance in F1, but also expressed his disappointment at lasting less than half a season.
"A short note from me… After recent events, I decided to take some time for myself away from social media, which I will continue to do," De Vries wrote on Instagram.
"I would like to thank Red Bull and Scuderia AlphaTauri for the opportunity to live my dream. Of course, it hurts that the F1 chance I dreamed of for so long ended prematurely.
"But life is not a destination, it’s a journey, and sometimes you have to take the hard road to get where you want to be.
"I am grateful for our privileged lives, proud of our journey and my family. This is just another experience; we move on and look forward to the next chapter.
"Thank you to everyone for your kind and encouraging messages in the past week. It’s been heart-warming to feel your support."
