The post attracted almost 100 comments including from fellow MAFS contestant Ben Blackwell.
"Chin up man, hit me up whenever," Blackwell wrote.
Others praised Daniels for being open and honest, while expressing their sympathy for his predicament.
The move comes just days after Daniels revealed he and his fellow cast mates were paid $60 per day to appear on the show, saying he lost "thousands of dollars" in the process.
Daniels posted an image to Instagram earlier this week, showing a legal bill for more than $3,200, after he and his mother sought legal advice on getting his marriage annulled.
In a statement this week, MediaWorks said it had been clear from the outset what was involved in signing on to the production.
"It was made very clear to all MAFS NZ participants what they could expect from taking part in the production. Including having to put their jobs on hold to partake in the experiment and agreeing to and understanding the laws of marriage, which state that a dissolution can only happen after a two-year separation.
"It was entirely Haydn's choice to take time off work to be part of the experiment and subsequently to seek legal advice around an annulment."
In an interview with The Hits this week Daniels said his experience on the show was "10 times worse" than he could've imagined.
"I was just emotionally drained. I was sleeping in until 10 in the morning, I was exhausted," he told hosts Stace and Flynny.
While he said he did not regret going on the show, Daniels admitted he probably wouldn't go back on the show knowing what he now knows.
Daniels' and Clarke's relationship has been the bane of the MediaWorks' PR team since before the show started, when word leaked that the match had not worked out at all well.
During the series, in real time, both he and Clarke posted messages to social media, telling folks that things were not good, with both having to delete the posts and carry on.
Last weekend he got called out by MediaWorks PR for not asking permission to talk to the Herald on Sunday, re him and fellow contestant Luke Cederman's decision to sell their wedding rings to raise money for KidsCan.
"That was it for me, I have had three months of being controlled and manipulated and enough was enough," he told Spy.
