Unless there is something specifically listed in the yellow pages of your phone book under cousellors that suggests they deal with anger management, I would just go through the list and start phoning them and ask.

Thanks, I am starting with talking to a counselor at school. I don't have a lot of money right now.

Took me a long time to realize that there are many different 'schools of thought' with therapists. That some of them might not have the same goals as I. Therefore, who ever you go to, ask questions as you would for any other consumer service. Find out what their philosophy is and how they plan to treat your situation. See if you feel comfortable with them and that they are giving you logical and personal (for your problem) advice.
School IMO is a good place to start. LOL, you are probably paying for that service anyway in the cost of your tuition. (My school has a Health Fee, I've argued with them that I don't want to pay it because I have insurance but they say they have to collect it anyway, SO, I go to that therapist, just because I've paid for it, haha).
Anyway, a few other things you could do, are there any clinics in your area that charge on a 'sliding scale'? Or professional associations that you can call to get a recommendation. Maybe on line look up (whatever the name is) association of Physiologists to find one.

I was wondering if there were free sources of councliing or support groups for anger management like the YMCA or other groups like them??

Thanks.

I found an EA Emotions Anonymous in my area so that will probably help.
Thanks for the helpful suggestions.
