You've had a rough count in your head for awhile, and you'll be sad to see that people you thought wouldn't miss it just can't make it. Try not to take it to heart, because summer is a busy season for all with vacations planned months in advance. Remember that the people coming to celebrate with you are doing so out of love. They are coming to share in your joy. The people who can't come don't hate you. They are quite overjoyed for your union, but they will have a glass of champagne for you elsewhere. Remind yourself to feel the warmth of that bond as well.
I won't say don't stress. I know that you will. I know that I do. You'll just have to take deep breaths and count each one as they come in. You'll have stragglers too. You'll be so mad when the date you've set for RSVP's to return by passes and you have to call people. Remember that your life revolves around your wedding, but they have a million others things going on. They didn't want to stress you out so try to have patience. It is much easier said than done I know. I'll try to practice what I preach!
How do you de-stress?
