• Robert and Diane Witt were found dead in their home in Worcester, Massachusetts
  • When Witt called for help, she was told of their passing by a cop
  • No cause of death has been released as the family is keen on their privacy

Alicia Witt is opening up about the myriad of emotions she went through after losing her parents a month ago. Witt's parents were found dead in their Massachusetts home just a few days before Christmas. The "Walking Dead" alum took to social media to write a lengthy and detailed post about how "it still doesn’t feel real."

Sharing the post on both Facebook and Instagram, Witt wrote, "It’s been a month since I got scared, not having heard back from them, and called to have them checked on. waiting, phone in hand, praying fervently that the next call would be from them, angry I’d gotten someone else involved."

The 46-year-old revealed that she realized "as soon as I heard the detective’s voice on the other line that they were gone. Knowing I would never hear their voices again. Beginning the rest of my life of finding them on the breeze, in a song, in a dream."

The actress revealed she was able to "quietly travel" to Worcester earlier this month to attend a "beautiful service and burial, to mourn and to celebrate them in total privacy." Witt also thanked the Mercadante Funeral Home for "going to great lengths to make this possible," adding that she will "will forever be indebted" to them.

"Thank you, also, to all those who have reached out with your memories about my parents. They were brilliant educators, deeply kind, curious, intuitive, wise, young at heart, funny — there will never be enough adjectives to describe them," she said.

"The circumstances around my parents' sudden passings have become fodder for the press, and there are some misconceptions rolling around — understandably so," Witt continued. "This is very delicate for me to write because I'm wanting to honor their privacy, which they held so tightly. There's an awful irony in the fact that because of the very lengths they went to in order to protect their privacy in life — that privacy has been stripped away in death.

"I never imagined I would have to talk about this publicly — much less, amidst overwhelming floods of grief. I hadn't been allowed inside my parents' home for well over a decade; every time I offered to have something repaired for them, they refused to allow workers into their house."

"I begged, cried, tried to reason with them, tried to convince them to let me help them move - but every time, they became furious with me, telling me I had no right to tell them how to live their lives and that they had it all under control. It was not for a lack of trying on my part or the part of other people who loved them."

Concluding her post, the actress briefly recalled her final conversation with her parents. "Our last words to each other were 'I love you,' " she said. "That part was simple; never in doubt. They loved me so. I loved them so."

While Robert and Diane's cause of death is yet to be released, authorities at the scene found no signs of noxious gases and did not suspect apparent trauma had occurred. The local newspaper added that "freezing temperatures, a malfunctioning furnace, a temporary space heater and a home in need of repairs" were potential contributors to their deaths, according to Telegram & Gazzette.
