I feel angry everyday especially when i am at work, i often break pens and want to punch a wall. what could be causing this?

Broken pens: Do you like your job? Do you have any issues at home? Is your anger and tension new, or have you experienced this before? How are you at encouraging and supporting yourself in your own self-talk? These questions could help uncover some causes for your being so tense at work. Talking with a counselor or therapist can help you figure thus out and learn some things to do to help yourself.
