Anger issues

I have no idea what’s going on with me, but for the last few weeks I have been so angry all the time that I get to the point where I’m so built up I could cry. I’m not happy in my job, and no longer want to be there so I think this is the main cause of the issue and I am working on getting out of there. But the smallest of things can set me off and it’s so debilitating. Has anyone else ever experienced an uncontrollable emotion of anger for a period of time and may have some advice on how I can manage it?
