Now this doesn't apply to everything, but it does apply to alot of things. Generally if you are quote on quote "still" mad about something, its been long enough and its time to let it go. Now we all process stuff at our own pace, so this isnt a way of saying your feelings aren't valid, but that maybe if you are *still* holding on to something, it may have turned into a grudge. Adding the term *still* in there implies that you yourself may subconsciously recognize this has already been strung on too long.
