Getting cold feel 35 days before my wedding 😖

I've been engaged to the man of my dreams for 9 months and we are getting married September 2nd. We've been together 1.5 years. Lately, I've been getting pretty anxious thinking about it. It's not wedding stress because we are eloping (alone) and the whole trip is already planned. I just want to know if anyone else felt this way before they got married? Is this normal? When I think about my future, I see him by my side. I don't know what my deal is. Please help 😭
