Does prescription medication actually work with anxiety and panic.

Every day I am struggling, I have GAD and apparently one of my new anxieties is work. I physically feel like I cannot cope anymore and I'm so close to quitting despite this being a good job.

Will medication help? How long should you give it? What works best with GAD so I can discuss it with my GP.

I've tried therapy and it just makes me feel awful and I end up giving up.

All help is welcome, I feel so awful and I just want it all to stop so badly.
