Yes, you will get thru the bitterness and anger. I am a year out of d-day, and I still have some anger, but not nearly as much.
I was also VERY bitter for quite a while, which came out as sarcasm. That too is fading, as I am finally moving forward with MY life, and looking forward to dating again and experiencing new things.
ThriveNotSurvive is correct, you need to allow yourself to feel your feelings and emotions, and try go work thru them in healthy ways, with healthy outlets for your anger and bitterness.
But after a while, you have to get to a point where you decide enough is enough, I don't want to be bitter and angry anymore, this is not a fun way to live, and then start moving forward.
Seems like this is all really fresh for you yet, so give yourself some time, and allow yourself to wallow and be angry and bitter for a little while, because working thru our feelings is so much better than stuffing them, and then releasing them later in inappropriate ways.
