Baby Steps

At first. It seems like everything is going perfect. That it won't take any time at all to fix what took you so little time to mess up.
Then as time goes on, you realize, that the pain you caused runs so deep, that it will take more effort than you have ever exerted on anything, to even get back to neutral.
But it can't all come at once. You can't burn someone alive and then just throw them into a tub of ice. It doesn't work like that.
Each time, it hurts a little less, and then before you know it starts to get better.
But you must take baby steps.
