Tiny Buddha website has multiple articles on dealing with anger. Go to the Home page and do a search on “Anger issue.”

With that said, we learn how to survive and behave from our caregivers, usually that means our parent(s).

You said that you’ve also fought with your mother plus you are going through puberty.  Both are ingredients for having a hard time controlling/managing/being aware of your emotions at the time they bubble up.

You said that you can simmer down when you go into your bedroom.  Why don’t you give yourself a timeout before things get out of hand?  Go off to your bedroom before the anger totally consumes you while letting your mother know you are going off to cool off by yourself.  Let your mother before the next argument that this is what you are trying to do to address your anger issue and then she would know to give you space and time to calm down by yourself.

Let your mother know what you have shared with us, i.e. you are struggling with how you express your anger and want to change your behavior.  This way she can help you or at least be aware of what is going on inside with you.

Check out the Tiny Buddha articles as well.

Good for you for being aware of your issue and wanting to change it.
