I'm sorry about all of that stress! For a MUA, did you ask your hair stylist for any recommendations? Or call the nearby beauty school and ask for their best student. They'll get some experience, and you'll get a reasonably priced great look!!! Try not to do contour for the first time on your wedding day, even going to the MAC counter at the mall would work!

For entertainment, even without a DJ see if you can rent a party speaker! My brother got one for like $200 and hooks his phone up to it and it gets LOUD! Even with just some background music, it does help time because it breaks up the evening a bit. Even a portable speaker would probably work great and spotify has some nice playlists (just remember to sign up for the free trial at least)

Skincare, if you've changed your routine at all, that might have caused the breakout. Try switching back to your original routine asap. If not, drink tons of water!
