Yes it does feel like that -- for men in particular we want to fix things now! It can also feel like every interaction is incredibly important and takes on so much gravitas which makes you feel like you have to do and say everything absolutely correctly.
In reality there is never a quick fix, putting things back right takes lots of time, it's a marathon not a sprint.
Your best prescription is to give her more space than she wants and focus on you and not her. She will do what she wants and you can either fight her or stay out of the way, but you really can't change her frame of mind through a frontal assault.
Instead you have to back WAY off, slowly make your changes and she will notice. I often tell people that the shortest path back together is a straight line in the opposite direction. If you can drop the rope and just let her go you stand the very best chance of getting her back.
