Mom's Posthumous Letter Is An Unforgettable Reminder That 'Every Day Matters'

"Please do me a favor and take a few minutes each day to acknowledge the fragile adventure that is this crazy life."

Two years ago, Wisconsin mom Heather McManamy was diagnosed with terminal breast cancer. On Wednesday, she died, but she didn't lose the battle.

McManamy's husband, Jeff, published a hilarious and heartbreaking letter written by his wife on Facebook Thursday.

So…I have some good news and some bad news. The bad news is, apparently, I’m dead. Good news, if you’re reading this, is that you are most definitely not (unless they have wifi in the afterlife). Yes, this sucks. It sucks beyond words, but I’m just so damn glad I lived a life so full of love, joy and amazing friends. I am lucky to honestly say that I have zero regrets and I spent every ounce of energy I had living life to the fullest. I love you all and thank you for this awesome life.

McManamy, who made headlines back in July for writing letters to her 4-year-old daughter, Brianna, to read as she grows up, asked her loved ones not to tell Brianna that she is in heaven. Her family is not religious and she does not want the little girl thinking she'd rather be anywhere but with her.

"I love nothing more than being her mommy. Nothing. Every moment with her was a happiness I couldn’t even imagine until she came crashing into our world."

She refused to surrender to the word "loss."

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

She thanked her husband for a "breathtaking life" and asked those who attend her funeral to celebrate.

If you go to my funeral, please run up a bar tab that would make me proud. Heck, blast “Keg on My Coffin” and dance on the bar for me (because there had better be a dance party at some point). Celebrate the beauty of life with a kickass party because you know that’s what I want and I believe that in a weird way, I will find a way to be there too (you know how much I hate missing out on fun). I look forward to haunting each one of you, so this isn’t so much a goodbye as it is see you later Please do me a favor and take a few minutes each day to acknowledge the fragile adventure that is this crazy life. Don’t ever forget: every day matters.
