Help! Wedding anxiety (exsisting anxiety disorder)?

I hope someone is still reading this, I googled and found this site. I am getting married this april and suffer from nxiety, I have not had an attack in awhile but I still feel symptoms everyday especially when driving. I used to could handle anything before I had anxiety issues but now I am so afraid of life. I don’t like being the center of attention but I used to. Recently I had a high school choir reunion ( I have been out of school for 4 years) I thought it would be fun like old times, but the second I got on stage, panic attack! I felt like I was going to pass out and while I sang I would not breathe well so half the time I just mouthed the words. I worry that the ceremony at my wedding will be like that too and walking down the aisle, I am so nervous. Also my fiance and I have waited to have sex until we are married and I am so anxious about that. Since the anxiety started its really hard for me to handle stress. Can anyone help or relate?

a self help book on overcoming panic attacks has all the info you need

breathe deep and slow with frequent stretches and take lots of valium before the wedding
dont tense up or fight back against the anxiety or fear
