Over editing!

This is a collage I created of imagery from "Mean Boys".
 I've finished editing the first 5 chapters of 28 and it wasn't easy.  I'm finding that my book needs lots of work, as it should, but also I feel that I'm over editing if that makes sense.  I've only started editing but I'm obsessing over silly things in the book like certain words that are being overused.  Words that must be used for a sentence to make sense.  I want to do three big edits and that's it because I don't want to memorize my story or forever editing it.  The more I read it the more I hate it, I'm sure these are the emotions most authors go through during this phase.  I might have to start searching for beta readers even sooner than I thought and I'm so nervous about that.
 My interest to read has increased ever since I started watching booktube and I'm so happy about that.  After becoming a working adult my reading has been terrible, everything gets in the way.  I realized I've been forcing myself to read books I don't like.  They either don't excite me, are over-hyped, or involve too much romance (I don't like books strictly with romance or a romance that takes over the plot).  This specific channel Jen Campbell is my favorite, I've been going through all of her videos, they're amazing and calming in a way.  She's opened my eyes to books I wouldn't have thought of reading.  
 Hopefully I'll continue editing at this nice pace and not pull all my hair out.
