One reason weddings can become a stressful process is trying to keep up with all the expectations with family and friends.
How can you eliminate this Problem? Know that no wedding will satisfy everyone and as long as it satisfies you and your partner that is all that really matters.
Try to prioritize your wedding tasks and decisions and start early.
Remember who is in control of this big day. Make sure you just communicate with the person or persons helping you plan in a calm way.
Note that not everything is not always perfect and sometimes trying to make everything just exact will stress you out in it self. Stay calm and everything will fall into place.
