Petunia...you bring up a very perceptive point here for me also, as anger was ever present in my own childhood home, while I was never allowed to express it myself!
I also turn the anger mostly on myself as self-blame.
I do recall vividly, after getting away from my home and experiencing the freedom of being on a college campus, the I experienced great, almost uncontrollable rage at having to return to the home environment periodically.
Of course, there was no one to relate this anger too, but I had private "fits!" I don't recall that I've ever experienced or expressed such anger since then, just become more accepting of limitations, I guess!
