I would offer this.....I do not know the reasons of what occurred with your friend...yet just the statement...."I cut a really good friend out of my life yesterday.".......If that person had been a good friend....and you reached the stage where you were willing...to cut them out of your life...and then go forward and act upon it....leads me to think....that what ever happened...there must have been a line they crossed.....that there was no stepping away from....

If it wasn't just a spur of the moment reaction....then you had to have thought about it for some time...and for me...there is that part.....where things keep going round and round in your head...and you...think about what to do....what to say....how you feel....you have conversations with yourself in your head....You reached a point where goodbye was your action....so in that process you may have dealt with your sad already....you may have grieved this loss for sometime before you acted upon it.....

Of course I am creating thoughts from my own experience...not really knowing yours......yet maybe what you feel now....is all the anxiety that leads up to making a decision....is behind you....you took action and now you just feel relief...sometimes letting go of people...is the very most healthy....positive thing you can do for your own life.....it doesn't mean it is a bad thing....if may be the moment you can breathe more freely....arriving.....

I hope you come to peace with within....
