“Instead of sitting at home feeling sorry for myself, I read a lot of really nice and encouraging emails” from her essay’s readers, Ms. Rubio wrote in a blog post soon afterward. “It sounds like dating sites are going to be inundated with cancer patients now. Good. Feel free to use my opening line.”
Ms. Rubio succeeded in finding love. An obituary on her Facebook page noted that her boyfriend, the photographer Mathew Zucker, “didn’t leave hospice for two weeks and was at her side when the cancer finally ended her life.”
Josefina Maria Ana Rubio was born to Salvador and Kathy (Varga) Rubio in Brownsville, Tex., on Oct. 12, 1977. The family moved to Solon, Ohio, a suburb of Cleveland, where she grew up. Her father died while she was young. .
She earned a journalism degree from Ohio State University in 1998, then spent about a decade as a staff writer at Columbus Monthly magazine in Ohio.
Ms. Rubio later worked as a writer and editor at VIVmag, a digital women’s magazine; as a social media director and writer at ih8exercise.com, a website dedicated to turning couch potatoes into gym rats; and a contributing writer for dealnews.com, a comparison shopping, consumer news and product-review site. In recent years she was an interactive producer for the Guggenheim Museum and a freelance writer.
Ms. Rubio, who lived in the Red Hook section of Brooklyn, is survived by her mother and boyfriend.
“In the end, my heart will stop, but it feels broken now,” Ms. Rubio wrote in her penultimate post, “The Worst Thing.” “I don’t want to leave the cats. I don’t want to leave my boyfriend. I don’t want to leave my mom. I don’t want to leave my friends.”
“I’ve had a good life. I can’t comprehend that it’s going to stop so soon. How did this happen?”
