Overcoming re-writing woes

What are some things you use to help with getting through major edits/ re-writes?

I am in the middle of editing one of my favorite stories I’ve written to date. One that i feel has promise for publishing (no its not my first ever written works) and i realized i had some really big structural issues. So putting my editor hat on I listed out what needed to change that made it make WAY more sense. (I am more of a discovery writer who’s finally learning some plotting thanks to the 5YP) I got super excited to dive back in however I’m having to rewrite very large sections of the text. Due to this…..I’m STRUGGLING! My brain is like “we’ve already done this. Why are we doing this again?!” And the editor me is like “because it’ll be BETTER,” and yet i still find myself not near as excited to write this as I was the first time.

I do really love what I’ve re-written and I know this major revision will put me much closer to where i want to be, and I’ll most assuredly be getting an editor after this because i know seeing the forest for the trees is going to be really hard. I appreciate any help or encouragement ya’ll could given me!
