2 months to go and i'm losing my mind! Help

Hey y'all,
my wedding is now a short 2 months away and i'm planning it ... ALL. I've never done any of this before and now i'm losing my mind? Every detail and plan leads to a new worm hole, decision and more stress lol. Any one else in this boat with me?
I feel like i was doing so well at the beginning and got all my vendors, but now i'm panicking thinking there's things i'm missing and details i haven't thought of. I'm on a strict budget so i didn't hire a coordinator and don't know anything about rehearsal dinners or days or before or timelines or this or that and come the day of i just want to get married and have fun. Help me 💗
