ACT - Expanding emotions - Anger

My therapist has recommended Acceptance and Commitment Therapy (ACT) and suggested I read The Happiness Trap. The book advises that rather than constrict emotions, you should expand them. To do this it talks about focusing on one emotion that you are feeling, "breathing" into that emotion, giving it as much space in you as it wants, and accepting it as just the sensation that it is. It says you shouldn't judge the emotion at all, but only notice its "physical" characteristics.

I have been doing this for about a week now, mainly on a ball of tension that I have on the back left side of my head, which feels like a pool of anger. I have, however, found that letting this anger "run free" has resulted in a lot of residual anger being left in me, even after I have stopped "practicing" the expansion. The downside to this is that when I feel angry I find it a lot more difficult to think straight, and I also find it very tiring.

I would appreciate hearing from anyone who has a good understanding ACT, or who has tried to apply it to feelings of anger. I'd like to know why I am supposed to be expanding the anger? Is it freeing the anger, which will eventually allow it to move on? Or is the point simply to learn to live with the anger? If so, it doesn't feel beneficial to have to deal with the tiredness and impairment to thinking that comes along with accepting the emotion.

My therapist is away on holiday for the next 2 weeks, so it would be great if anyone can help out now.

Just wonder if anyone had any thoughts?

Thanks

Hi!
I was also recommended ACT but in Sweden we don't have my therapists.
I have however been through DBT and PDT for borderline related issues and I have found out I am very very angry a lot.
I am a quiet borderline nowadays. Before, I could get rages towards mostly boyfriends but not anymore.

During my PDT, my therapist also told and taught me how to identify my anger and "let it float free" and don't be scared about it.

But I get angry a LOT. And I do not know what to do with it. It consumes my brain. I cannot think straight and I cannot sleep at night when I am angry. I have NO IDEA how to handle anger management. I asked my therapist and she told me to bring it all up with her. But I stopped going to her due to several reasons and it didn't help to bring it up. It just turned into a complaint session.

Have you had any luck yet?
