I've heard therapy is expensive. What can you do if you don't have the money for it?

Don't say get a job. I have one, and the person who needs it has one, too. The problem in question is anger issues; getting furiously angry over very small, trivial things all the time, to the point of breaking things in blind rage and screaming out profanities at the top of their lungs. On a daily basis, often 2 or 3 times per day.
