"I am grateful for my entire family, my long time girlfriend, Amber, and friends as we prepare to celebrate a glorious new year together," wrote Robins, who is celebrating the one-year anniversary of coming home from the hospital after a life-saving bone-marrow transplant. She had been diagnosed with from myelodysplastic syndrome (MDS) in 2012.

While Roberts, 53, has reportedly been out in her private life and to the GMA team, this is the first public mention of her sexuality.

The Facebook message in full:

Flashback 12/29/12....Hard to believe this was 1 year ago today..when I reached a critical milestone of 100 days post transplant...and KJ was finally allowed to come back home.

Reading this comforts me and I hope the same for you: "If you are depressed, you are living in the past. If you are anxious, you are living in the future. If you are at peace, you are living in the present."

At this moment I am at peace and filled with joy and gratitude.

I am grateful to God, my doctors and nurses for my restored good health.

I am grateful for my sister, Sally-Ann, for being my donor and giving me the gift of life.

I am grateful for my entire family, my long time girlfriend, Amber, and friends as we prepare to celebrate a glorious new year together.

I am grateful for the many prayers and well wishes for my recovery. I return every one of them to you 100 fold.

On this last Sunday of 2013 I encourage you to reflect on what you are grateful for too.

Wishing you a Healthy and Happy New Year.

Roberts has been with Laign, a massage therapist, for 10 years. Fellow Good Morning America veteran Sam Champion came out last year, and has since married partner Rubem Robierb.
