Wedding getting out of hand

Diana

So I just recently got engaged it was all great, up in till the whole wedding planning started! At the beginning I was absolutely against having/doing anything I wanted to save up for a vacation since my fiancé and I haven’t traveled much. My fiancé really wanted to celebrate at least a little. For a while I was sticking to my guns about not doing anything at all. Slowly we went from nothing at all to a little bbq to civil wedding on my parents land to now actually looking at venues. I wanted 100 guests tops and that’s it. Well we got around to making a guest list and we have 200 people with just family. The ball keeps rolling and idk what to do anymore I want something with some family there but everyone just keeps on getting excited for our wedding I just started planning and I’m already stressed and overwhelmed and planning an over the top wedding! Any advice?
