My Eczema is Coming Back and i Don't Know What to Do

When I was younger (about 8-13 years old) I had had eczema that would get all over my face, legs, arms, feet etc. I thought I was done dealing with it but now more than a decade later its come back out of nowhere literally just in time for my wedding. I woke up two days ago and noticed some eczema on my forehead and a little bit around my eyes. When I woke up this morning, there were patches all over my face and even some on my feet and legs now. My face swole up when I tried to do my makeup this morning and my normal tennis shoes were really uncomfortable. My dermatologist said that I can't wear makeup for at least a week and the wedding is tomorrow. What should I do? I know I'll look ridiculous walking down the aisle with crusty patches all over my body and I probably won't even be able to wear the cute heels I picked because my feet are so irritated. Not to mention I wear makeup every day and feel super insecure without it. It's getting to the point where I just can't imagine going through with this looking the way I do. I feel just like the little girl fifteen years ago who was bullied every day for her gross skin.
