Hi Michelle,

Post surgery depression is very common. This should be reported to her DR maybe not carido but her G.P. Have you asked her why ? Just letting her talk alot to family and friends keeping close contact may help more than you even think. Try to engage her in fun activites she use to like to do. Just her being in the state of trying to recovery physcially and then add other life stress to that--- can easily lead her into depression. Being it also was heart surgery its scary --many people start to question there own mortality. She may have combo of post traumatic stress disorder as well as depression. She really needs to be seen and talk to her G.P they might be able to put her on meds to help adjust her serotonin levels. Best of luck and im very glad you seeking out help for your mom.
