I was like that after he left, have the same feelings, It was crazy now that I look back, it was easy for him the no contact, for me has been torture, 16+ years with this man and he just moved on.
I had to hit my pillow a dozen times just to get the anger and the tears out, now is just part of my ES&H. Things will get better, it is OK to feel. The pain will diminish a lot, mine still there but just barely. Good luck to all of you that are going thru a breakup, you are really breaking free...better things are coming your way...trust your HP.
