Like I want to be angry for a bit longer first? why would I want to be like that?
What does your anger give you Fleur? I think it must be giving you something positive in the short term to want to hold onto it.

For me, when I am angry with others and holding onto it, my anger gives me a sense of (false) energy about the situation (especially if there isn't actually anything I can do to change it) and it keeps me feeling like I am in the right, I am ok. It's kind of self affirming in a way. Anger is usually a cover-up emotion for something else. It is the great pretender and hides a multitude of other feelings, like an iceberg, most of it is submerged underneath.
