Consider whether your offense is realistic based on the gravity of the obnoxious behavior or a response to deep-seated insecurity that you have. Often, we experience "countertransference," used in psychodynamic psychotherapy, which distorts our perceptions of others due to our own insecurities. For example, you become enraged at a co-worker who pokes fun at the vacation photo you just put on your desk. The remark was not really that hostile, but it reminds you of your childhood feelings when your brother taunted you.
