I am currently taking some time away from my long term counselor and seeing someone about anger manageme...
Anger management can be used to cope with totally justifiable anger. Honestly its very rarely that we are angry without ANY justifiable reason, there is normally something, whether past or present.
I don't know how your sessions are going, but I found as a kid focusing on why I was getting angry, how I reacted and then alternative reactions as well as ways to cope with the anger worked well. I personally grew up around one very depressed and angry parent who had to go to anger management, so sent me as well. Couldn't admit it may have been just him who was freaking mental. *grumbles*.
ANYHOW it did help cope with irritants and my reactions to them. I think as long as large triggers are around its not going to just go away, but you can learn to channel it into other things, and maybe one day you will decide its not worth living a half life for 'all you have worked for', but thats a big step, and may not even be true.
Good luck! Angers never a nice thing to be dealing with, for you or anyone else.
