Choices: Both are SSRi. As,to which is better,that is hard to say. You could talk to your physician about Pharmacogenomics testing to decide which is best.

PANIC: Best to discuss medication with your Psychiatrist. If uncomfortable with your Dr. consult another for a second opinion. Have a physical exam by a Dr. to determine if you have a physical illness. Consult with a Clinical Psychologist for psychotherapy with ZOOM sessions. Fears and anxiety could be heightened because of the Covid-19 pandemic. Stay safe & hopeful to elevate your immune system.
