The TV presenter, 28, shared a touching message with his 3.91 million combined Instagram and Twitter followers on New Year's Eve as he prepared to welcome in 2016.
The Take Me Out: The Gossip host made us feel emotional as he posted a moving tribute to his wife and late grandma.
He wrote: "Life is all about ups & downs. This year 1 special woman vowed to be in my life forever and 1 special woman left my life forever... Be prepared for the best & worst moments."
Clearly in a reflective mood, Mark added: "Just make sure in 2016 you take the best out of every moment and never take anyone or anything for granted.
"Happy new year people. Lots of love and happiness to you all. Xx"
Fans were quick to show their support, with one responding: "Lovely words @wrighty_ .... She will b looking down very proud of u all...."
Another wrote: "Aww this has really touched me Mark."
Mark married actress Michelle in a stunning May ceremony surrounded by friends and family, including his beloved Nanny Pat.
But tragically, the TOWIE favourite passed away in December following a short illness.
At the time, a devastated Mark took to Twitter to say: "My heart is broken but so overwhelmed by your support. To know good ole Nanny was loved by so many is the best feeling in the world Thank you."
His wife Michelle, meanwhile, wrote: "Heaven gained an angel today."
Her family issued a statement on 16 December saying: "Sadly our amazing, courageous and beautiful Nanny Pat passed away this morning after a short illness. We are overwhelmed by sadness, and the whole family ask for privacy at this horrible time."
Nanny Pat had been a TOWIE favourite since the first series when she introduced us to her sausage plait. Over the years, she became a fan favourite thanks to her pearls of wisdom, unwavering devotion to her family and comic timing.
