I am a 64 years old female who had mitral valve replacement as well as a pacemaker surgery in March 2016. Most days I am depressed and anxious about dying and getting a heart valve infection. I used to be depressed before the surgery as well as anxious but it has worsen. I feel listless. I had been to the psychiatrist but sertraline indicated put my anxiety thru the roof and bipolar med lamtox gave me dry mouth. Also I am worried the meds will affect heart and other organs. Thank you for any advise and comfort you can give me.
