Reddit reviews ACT on Life Not on Anger: The New Acceptance and Commitment Therapy Guide to Problem Anger

There is a book (ACT on Life, Not Anger), which I have not read. My guess is the authors probably focus on how the anger is negatively affecting the client's ability to live their values, using acceptance to hold the emotion while behaving in a more values-consistent manner.

That said, I think a more affect-oriented approach like Emotion-Focused Therapy would be a good adjunct. Intense anger is often a secondary emotion (in ACT terms, experiential avoidance; in psychodynamic terms, a defense); an attempt to deal with more scary and vulnerable emotions like fear or grief that occur in a more primary position. ACT doesn't really have a very systematic way of working with the different layers of emotion. Mindfulness can certainly be helpful, but can quickly turn into a strategy for experiential avoidance with clients who have lifelong issues with overwhelming emotions.

u/TheHeartOfTuxes has it pretty well scoped.. to which I will (however egotistically) add that it pretty well always comes down to...

1. understanding why one might have such reactions so that one can get up out of the cycle of rage which operates a lot like the cycle of addiction (and understanding them both is usually highly useful and productive); and
   
   
2. what to do about them IF one wants to "delete" them from one's list of behavioral urges and options.
   
   If one was neglected, ignored, abandoned, invalidated, insulted, rejected, disclaimed, criticized, judged, blamed, embarrassed, humiliated, victimized, demonized, persecuted, scapegoated, and/or otherwise abused by others in early life, one may have very good reasons to have a lot of unprocessed emotions about such treatment. Over time, one can be expected to become in-struct-ed, programmed, conditioned, socialized and/or normalized to various defense mechanisms to protect oneself against such emotions, including risky behaviors and expressions of anger than range from more indirect and passive to more direct and aggressive. The lock here is anger, and the key to it is using whatever it takes to digest, metabolize and process the neural energy of it.
   
   There are three basic ways to accomplish that:
   
   
3. Deal with the symptoms.
   
   . . . a) DBT provides training in four basic skills, including -- in effect -- "anger management." Another, somewhat similar system is the the 10 StEPs of Emotion Processing, which can be used to "bleed off" excess "pressure" in the fight-flight-freeze action of the ANS when it is triggered by anything perceived as threatening.
   
   . . . b) DBT, MBBT, and ACT all provide inexpensive workbooks for anger management. See this, and this, and this, all of which I have used and can recommend.
   
   
4. Deal with the cause.
   
   . . . a) EMDR, HBCT, SEPt, SP4T and NARM have all been shown to be highly effective at so doing.
   
   . . . b) To find the clinicians who know how to use these psychotherapies, look here, and here, and here, and (for DBT specialists in particular) here. If you dig a little on each page, you will be able to see which therapies they use. Most MD / psychiatrists, btw, are not therapists themselves (they are medication specialists), but can refer you to those who are, and are often -- though not always -- excellent sources of referral.
   
   
5. Deal with both.
   
   . . . a) I found that using Ogden's SP4T as the interoceptive 9th of the 10 StEPs of Emotion Processing gets the job done for me and others. But DBT, ACT, MBBT, MBCT, EMDR, HBCT, SPEt, SP4T and NARM are all useful for anger management and "digestion."
   
   I'd investigate all of this.

Maybe you could try some techniques from Acceptance and Commitment Therapy. The acceptance part helps you "let go of the past and move on with life" by helping you to stop struggling against the anger and misery, and the commitment part helps you decide what kind of person you want to be (e.g., someone who doesn't say mean things when angry, trusts others, reaches out to potential friends, or whatever it is that you want to be) and move towards becoming that person.
