After my last panic attack my GP prescribed me a cure of 6 months of antidepressant SSRI, have you ever tried them?

SSRI (Selective Serotonin Reuptake Inhibitors) are used to treat depression and panic attack. I also suffer from anxiety. I read the many side effects and I wonder, does it really work? Have you ever tried them?
