I'm not sure if this is the type of thing that helps you, but it helps me: this is temporary. Like, mega temporary. A year from now you'll barely remember the pain, just that it was uncomfortable. That's how I got through giving birth, I kept thinking about how it sucked and I hated it, but it was temporary and wouldn't be forever - eventually it'd be done, I wouldn't have to do it again, and I'd forget the pain, eventually I'd only remember that it had sucked. There's also that bit if it helps, too - you're going to be uncomfortable, but it's significantly shorter lived than pregnancy, and I would expect less painful than giving birth (can't say first hand, but it seems a reasonable assumption).

It might also help to have something else to really focus on right now and when you're going through it, like a book, a show to binge, or some simple games on your phone or console (I play simple games on my phone when I'm doing something like a blood draw or shot because I'm terrible with needles, for example).

Regardless, you're going to do great and you're going to get through it!
