Diane Costello

Age 66, of Philadelphia, Pennsylvania Passed away on November 4, 2025, at her residence.

Diane was the beloved sister of Frank, Kathy (deceased), and Nancy. She was the mother of three children who, despite life’s challenges, remained a part of her story. Diane faced her demons throughout her life and fought them in her own way.

Although she did not raise her children, she was — and will always be — their mother. Her journey was marked by struggle and resilience, and now she rests in peace, free from the burdens that once weighed her down.

Services and interment are private.

A note from her daughter, Christina:

Mom,It’s difficult to find the right words knowing that you’re gone. Even with all the years apart, your passing has left me with a mix of emotions that are hard to put into words. I’ve thought a lot about what your final days might have been like and hope, in some way, you found what you were searching for.

Life wasn’t easy for you, and I know you carried battles that few could understand. My hope is that you’ve finally found peace — free from the things that weighed on you in this life. You were my mother, and that truth remains, no matter the years or distance between us.

Give Aunt Kathy a hug, and I hope the two of you are together again, finding the comfort that may have been missing here.

With Love, Christina
