Can I give you some real advice:
whatever is worrying you this evening will not be the things you remember about your wedding in a few years time. Tomorrow will absolutley fly by, please take time during the day to think and remember, eg,
- this is how it feels to get up on the morning of my wedding,
2, this is how it feels to get ready for my wedding,
3, i'm going to walk down the eisle and return as a married women
4, this is my wedding happening right now
you get the picture. It will all pass in a heartbeat try to be present through the day. Don't drink too much, you'll want to remember as much as possible. Try to spend as much time with your husband during the day so you'll have memories you share.
Please don't worry about the details, they are not important at this stage and i'm sure you've spent many months making the arrangements you want. Can your ever remember attending a wedding and thinking it didn't go well because the bridesmaid didn't hold the bouquet during the service!
Have a wonderful day full of joy and happy memories. If i had a time machine i'd go back several years and give myself all of this advice the night before my wedding.
Congratulations xxxx
