Many of us on here can relate to what you are feeling and where you are Wagg mucker.
The aggression relieves the pain temporarily as does the Alc. But neither deal with the problem in the long term, and both compound the problem with the beast.
From experience, I would go looking for a scrap anywhere, Even some dick in the toilets at a McDonalds restaurant who splashed a few drops of water over me while washing his hands.
The Aggro took me that far that I lost my Misses, my Kid, my family home. and allmost my freedom. Even people who knew me before keep there distance these days because of the shit I used to do.
You need to get on a CBT course, and maybe an Anger management course. Both will give you a head start in getting a grip on it. There are also meds out there that help, but like all meds, they are just a cap and not a cure. You realy need to get to the heart of the problem.
The fact you are here talking about it, you allready know it has gone to far. We can also only assist you so far, there comes a point that you have to go do something about it yourself.
There realy are loads of things out there to help you, speak to a Therapist and find out what options they suggest and find out what is available in your neck of the woods.
I am off Meds, my Therapy from 2,5 years has ended and I have 2 clinics behind me. And still I am looking for any tid bit of help.
Couple of months back I started with Kinesiology, and for me it helps. But I am further down the road and what works for me maybe doesn`t work for you. But there comes a time and a state of mind where you will try anything.
Tuppence well spent I hope.
