I just wanted to say that I have heard many people spout off about "God never gives you more than you can handle." Well that is cow-dung. The truth is that God never gives you more than you and He together can handle, and He is the one doing most of the work.
Now is one of those times in life where you are meant to turn towards God, not away.
Having said that, Anger is an issue I have had to deal with. I do think you men have more anger issues to deal with than us ladies. Testosterone, or something.
Does physical exertion help you? Punching a punch-bag, go running, chop wood.
On the flip side, there is meditation, oil-painting, yoga.
I found that avoiding a certain person that made me angry, was a huge help. It's only after a couple of years of me ridding myself of that person, that I am in a headspace able to actually confront him, calmly and purposefully, about how he treated me.
Only you know the situations (or people) that make you angry. Can you walk away? If so, what is stopping you? Pride? Revenge? Can you explain to whoever causes the problem the effect it has on you?
Are you angry with yourself perhaps? - You haven't achieved what you thought you should, and maybe someone is reminding you of your "failure". People only put others down when they feel downtrodden/misunderstood themselves.
Count to ten? My Mum used to do this, when dealing with my Dad (they are now divorced), and it always made us kids laugh when she grit her teeth and growled "one, chew, chree, frrrr, freve, shicks, sheven, ..... and then she'd laugh too.
Don't let people tell you that no one can make you feel bad - that it is your choice. That is another myth, perpetuated by non-bipolar people and daytime talk-show hosts. Bipolar is full of emotions which are not normal/appropriate, and are blown all out of proportion. We don't just "get over it". Whenever someone tells me to "get over it", I ask "How". They can't give me an answer.
So anyway, welcome to the forum. I hope you find some help and cameraderie here. Oh, and I am a fan of firefighters. I work with them in summer. We have terrible bushfires in my part of the world.
God bless.
