Whenever I'm asked this question, I think of the poor bride who wrote this on a local message board:
“I hated all of the planning and felt so tired, stressed and sick of it all. I had so much stress even the week before and my venue treated me like dog doo doo the day and night before my event...I have been overcome with depression and anxiety over imperfect details. Most notably is that the day seems like a blur and this is most likely due to the fact that no matter how many times I asked, no one would get me some lunch...My husband felt as I did - starving! We felt like there were a million people around when we were taking pictures and no one thought to get some damn food. Anyway, I felt like this seriously compromised my day. The photos seem like a blur, not sure if they will even come out well, everything was so chaotic. We were 40 minutes late for pics. My bridesmaids would not let me wear a watch and yet kept horrible time. All I can think is that I wish I hadn't bought into what everyone was telling me about how this was my day, that everyone would take care of me, I could just relax and enjoy it, one BM said she promised that everything would be as I wanted...It was awful and my fault in it is that I should never have trusted or given others so much control and power over making sure I was taken care of.”
Here’s my short answer: People hire professional wedding planners so they can place their emotional investment in one person instead of many. They can enjoy the wedding while we manage the details, like making sure they’re fed.
