In a moving goodbye letter to her husband and daughter, Heather McManamy is very clear with her wishes.

Don't tell her daughter she's in heaven, never say she "lost to cancer," and make sure to dance at her funeral.

The 36-year-old's posthumous letter has gone viral after her husband Jeff posted the note to her Facebook page on Dec. 15, the day after she died.

 

Hello all,I am posting this on behalf of the love of my life. These are her words. Much love to all. - Jeff...

"Please, please, please do not tell Brianna that I am in heaven," McManamy wrote. "In her mind, that means that I chose to be somewhere else and left her. In reality, I did everything I could to be here with her, as there is nowhere, NOWHERE, I would rather be than with her and Jeff."

McManamy writes that her energy, love, laughter and memories remain with family, and she adds that she'll always be with them, "in as non-creepy as a way possible."

She also implores her loved ones to never say she lost her battle with metastatic cancer.

"Cancer may have taken almost everything from me, but it never took my love, or my hope, or my joy," she wrote. "It wasn't a ‘battle,’ it was just life, which is often brutally random and unfair. And that’s simply how it goes sometimes."

McManamy asks her family and friends to take a few minutes each day to "acknowledge the fragile adventure that is this crazy life."

"Don't ever forget: every day matters," she writes.

McManamy's letter has been shared more than 1,500 times since it was posted to Facebook.

Jeff McManamy wrote that he was overwhelmed by the outpouring of support.

"It's easy to forget sometimes, but seeing all of these posts and messages show how much good there is in the world," he wrote.

Jeff McManamy said after receiving such positive feedback to his wife's goodbye letter, he decided to share her obituary online, which Heather McManamy also wrote herself.

Wow, just wow. I can't believe the outpouring of support from all around the world. Thank you all so much! It's easy to...

A celebration of McManamy's life is set to take place Saturday.

"If you go to my funeral, please run up a bar tab that would make me proud," she wrote in her obituary. “And there had better be a dance party at some point."

Before her death, McManamy wrote a series of cards to her four-year-old daughter to open during the milestones in her life – from losing her first tooth to having a child of her own.

McManamy said she loved nothing more than being Brianna's mom.

She wrote: "Every moment with her was a happiness I couldn’t even imagine until she came crashing into our world."
