missmarch1978, Mark has already given you the important information, but I just thought I'd say that over time the symptoms do ease. I'm about 10 weeks out from a fairly similar hit to you, and had a lot of your symptoms to begin with, especially the nausea, headaches, dizziness etc. Over time they just get less and less. Early on I was getting major panic attacks at everything, talking to people, being in any environment bam panic attack. Now they've drastically reduced, as has the headaches, nausea.

They can still come back though, if I push too hard at work, too long infront of a screen I still get symptoms, but instead of lasting for a week they typically clear up with a good nights rest.

You won't find you wake up one day and feel a lot better, you'll likely find that when you look back to weeks or months prior your symptoms have drastically reduced, especially if you write them down and check that list after a month.
