Pregnancy after breast cancer.

All of their stories helped.

So I intend to be the same for others.

The Bachelor TV series

This is day one of sharing and is going to be a long one.

This first step of acceptance of my reality was the hardest.

But I am ready to fight this.

To my extraordinary husband to be@jarcuri I dont know how Id do this without you.

The selfless love that you smother me in is beyond anything I imagined Id be blessed with.

I love you to the fullest in this lifetime and the next.

Sharing with you was already the most helpful thing at this time.

The TV personality advocated for people to stay vigilant regardless of health or age and encouraged self-checks.

You spend a lot of time asking why.

Should I have worked out more?

Stopped taking birth control sooner?

Was it my deodorant?

What about eating more organic food?

Should I be vegan or carnivore?

Ultimately, I dont think Ill ever have an answer.

like stay proactive on [sic] your health and know that things are changing, she wrote.
