Cara Santana has been keeping her head high as she self-isolates from COVID-19.The 35-year-old Vida actress told the spring issue of Retreat Magazine, which hits newsstands on Friday, that she has felt 'anxiety' during this difficult time but has used journal writing, positive affirmations and a course on happiness from Yale University to stay balanced.'Having just celebrated 16 years of sobriety, I think being honest with who you are and taking the time to get to know yourself and to take a critical look at who you are is the most important thing you can do,' said the beauty who has been linked to Desperate Housewives star Jesse Metcalfe for 13 years.
