Wedding Stress and Bickering

We just found out that our planner had the wrong numbers in and was off by 6k. We are pretty upset but more upsetting is that we keep bickering. This wedding is costing so much and the stress and the checklist and the never ending stuff that needs to be done is wearing on us. We both have very intense careers and the wedding is taking the little energy we have left at the end of every day. We are trying hard to manage it and stay balanced but it’s not even fun anymore. Sucks.

Can anyone share some positivity or shed light or make suggestions that could help? I know I should shift my perspective and come from a place of gratitude but I’m just having a hard time. What is supposed to be a beautiful and romantic is anything but that right now 😢
