Yeah, first, you need a new doctor. Think about it -- he's not an expert in anxiety, didn't send you to a psychologist for therapy to see if it was anxiety (psychologists are experts in anxiety and can therefore diagnose it) before putting you not on just one but two very strong medications that are very hard to stop taking once you've been on them for a long time -- so much for first, do no harm. Anyway, now that you're here, antidepressants can take 4-6 weeks to start working, but again, they really aren't going to do anything for someone who had one anxiety attack, if that was what it was. And a GP can't diagnose it -- chronic anxiety that severely affects your life and therapy or other things don't fix it is when we need meds, but you had one event. It's really hard to diagnose from one event for anyone. A psychologist might talk to you a few times and get a sense of your life, but your GP doesn't do that. Unless there's a lot more to this story, such as a lot of anxious thinking over a period of time that has been interfering with your life, and you didn't mention that, I'd say you're still at square one. Are you a chronic anxiety sufferer? Is there a stressor in your life that might have triggered this? Because if not, if you don't sit around being anxious and this happened all of a sudden just once, it could be anything -- including things as minor as a bad day with insufficient sleep or hydration.
