Am I allowed to be ANGRY when I am on PC?

My T has been working with me, to help me to release the ANGER. I find it very hard as there is a lot of fear that goes with that feeling.

Obviously I need to express the ANGER in a safe way, and without upsetting anybody else.

I feel, (maybe because of my own issues)that this is frowned upon here at PC.

I would like your thoughts on this subject.

Thanks.
