Yes. Maybe the anger is justified, but is it helpful?

Being furious all the time is really hard on your body. It's hard on your relationships with other people.

Anger is useful in a fight where it can be used to overcome fear and ignore pain. But, it's hard to go to bed and get a good night's rest if you're still seething with anger.

Maybe, sometimes, anger can be a good thing in the long term if you want to maintain the energy needed to get a law changed or something. That's not something that happens overnight, and it's easy to get discouraged. But, you need to be able to balance that with being able to sleep properly, to socialize, to perform well enough at your job so you don't get fired and don't end up homeless.

If you just want to be angry, then stop wasting the therapist's time, and wasting your own money.
