My daughter had just started Kindergarten (wow, that's a trip down Memory Lane--7 years ago) when I took our new puppy outside for a potty break. She was impatient to get off the front stoop and pulled really hard on her leash, causing me to be pulled off balance. I knew the moment I stepped off the stoop that my leg was broken--the small leg bone right above the ankle bone.
Because of how I broke my leg/ankle, the Urgent Care personnel at first didn't think/believe I'd broke it until the X-ray came back showing the break. Then, because of where the break was, I had to wait until Monday (this happened on Friday) for the swelling to go down, and I had to see a Sports Medicine Specialist to make sure the leg/ankle/foot were properly aligned so that everything would heal right. I wore a removable boot--although I didn't get to remove the boot for a number of weeks. Having the break right there is very tricky to fix. The bone was slightly off, but luckily, it healed just fine without needing pins and surgery.
Breaking a bone in the foot is very hard to heal. Many people I know who have broken a bone in the foot who didn't listen to their doctor's advice have ended up having trouble with their foot to no end for the rest of their lives. Whatever the doctor says to do--listen and do it. Your feet bear all your weight, every day, whether standing or walking. You need your feet to get around and be independent. It behooves you to take care of yourself so that your foot can heal and so no complications arise.
Yes, you have a vision of "the perfect graduation party." That's great. As one poster stated, write down everything you'd like to see done, then delegate all the chores to neighbors, friends, and family members. Then LET GO of your expectations and just enjoy this special day with your daughter. A party should be for celebration and having fun. Really. I don't go home and remember all the nuts and bolts and pieces of a party; I remember the people I visited with and how happy the guest of honor was. All the other stuff is just minituae that no one is going to remember.
Your daughter, however, will remember who came to celebrate this special day with her. What will make her day even more special is knowing you're also enjoying her special day with her--not stuck in the kitchen, micromanaging everything.
Don't sweat what's inconsequential. Give your daughter a wonderful day--and ENJOY it with her! Perhaps having a broken foot is God/the Universe's way of asking you to please slow down, smell the roses, and BE THERE for your daughter that day, rather than running around, making sure all the i's and t's are dotted and crossed.
Have FUN.
