I know what you mean.
It took quite awhile to allow myself to feel the anger. I felt the fear first, then the sadness. They flipped flopped for awhile too. Those two emotions kept me quite busy much longer than I'm willing to admit. But as I worked through those, eventually the anger came along. That's the emotion that I'm least comfortable feeling as I had to deal with other people taking their anger out on me for so long, I thought that made me just as out of control and destructive as they obviously were. But I wasn't out of control or destructive....it just felt that way sometimes because anger was very new to me.
Don't worry, I'm sure your anger will surface when you are ready to deal with it.
