Hi.I'm 72 Years Old Female And Two Months Ago I

Hi.I'm 72 years old female and Two Months ago I had 3 stents placements in my heart. I take blood thinner (plavix) and Metoprolol and Lipitor. I have chest pain(4 from 10) and feeling weak and I cannot seep at night at all. My cardiologist says all is good and nothing wrong with stent placement. My family doctor prescribed Citalopram 10 and alprazolam 0.25 because he Thins I am suffering from depression. I have been taking Alprazolam for 25 days and I have't got better. I will start taking citalopram today . I did some research online I see shocking side effects of these medication. I don't know should I start taking citalopram or no.
