Hey Gloria

It has been my personal experience that anger is definitely part of depression.  It might be that you are close to understanding what things are bothering you.  Does your anger seem unpredictable or does it have a pattern?  What things are ticking you off?  Can you foresee your actions before they come?  What are your triggers?

When you get angry enough to throw things could you replace that behavior with some other action like working out, martial arts, or punching a pillow?  Some folk turn the energy from their anger into artistic pursuits like art or writing.  As far as cursing...sometimes I go into my shower and just scream.  You definitely need to get that anger out but in safe ways that won't hurt you, someone else, or your stuff.

An anger management class might be a great idea.  I don't know exactly what they do there but it might help you to understand your feelings more.  Talking to a counselor or therapist could also be of benefit.  You want to get to the point where you can understand the reasons behind your anger and deal with those issues directly. 

Hope this has been of help.  This is a great first step...that you are reaching out and thinking of ways to help yourself.  Please stop back and let us know how you are doing.
