(CNN) Former first lady Barbara Bush is in failing health, a source close to the Bush family tells CNN. 
 
 The source said she is being cared for at her home in Houston and has decided she does not want to go back into the hospital. She has been on oxygen for some time. 
 
 Her husband, former President George H. W. Bush is with her, as are daughter Doro and sons Marvin and Neil. Her other sons, former President George W. Bush and former Gov. Jeb Bush, have been in and out visiting her the past week. 
 
 Bush's office released a statement, confirming after a "recent series of hospitalizations," she has decided against seeking additional medical help and will instead focus on "comfort care." 
 
 "It will not surprise those who know her that Barbara Bush has been a rock in the face of her failing health, worrying not for herself — thanks to her abiding faith — but for others. She is surrounded by a family she adores, and appreciates the many kind messages and especially the prayers she is receiving," the statement continued.

– Barbara Bush is in failing health and won't be seeking further treatment for her illness, said a statement released Sunday. Per the AP, family spokesman Jim McGrath issued the news release saying that following a recent series of hospitalizations and after consulting with her family and doctors, the 92-year-old former first lady has decided not to seek additional medical treatment and will instead focus on comfort care. The release did not elaborate on the nature of Bush's health problems. However, CNN reports that Bush has been hospitalized multiple times in the last year in her battle with Chronic Obstructive Pulmonary Disease and congestive heart failure. McGrath says Bush appreciates the many kind messages and prayers she's been receiving. "It will not surprise those who know her that Barbara Bush has been a rock in the face of her failing health, worrying not for herself—thanks to her abiding faith—but for others. She is surrounded by a family she adores, and appreciates the many kind messages and especially the prayers she is receiving," the statement read. Barbara Bush has been married to George HW Bush for 73 years. In recent years, it has been her husband's health, not hers, that has made headlines. The 93-year-old 41st president was hospitalized in 2015 following a fall in the family home. In 2017, Bush was hospitalized twice for a recurring case of pneumonia, the first of which kept him away from home over two weeks.
