Getting married in 10 days. Having panic attacks... Help!

I love the guy I'm marrying. It's taking place after 2 years of struggle in convincing our parents. And now that it's happening, I'm more anxious than happy. I have anxiety disorder and every day, i go through very bad panic attacks. I don't wanna cancel the wedding and I can't bear this constant panic situation. I'm scared of how my life will change. Please suggest what to do in a situation like this. Is it normal for women to go through this ?
