Help find Rebecca

My name is Nancy Swafford, I am the sister of Rebecca Demory who had gone missing after leaving the hospital in Odessa, Texas February 28. The police found her car in the same spot she left it when she was taken by ambulance to the hospital. Her last text which was to our mother said "I am going home today” but she never made it. It has now been 3 months since my sister went missing. My family is pleading for help.
