Whether it’s a disagreement with someone of any kind, a less-than-perfect work situation, or you’re lacking in self care, whatever the difficult situation is, do not blame others. Sure, it might be their “fault,” and if they had just acted a little more responsibly then all would be ok. That’s water under the bridge right now, the more important question is where to go from here, and for that you can always be responsible. Victims come from the place of blaming others. People who are causing their own life think instead about what is missing, and what can be done to change the unfavorable situation.
Come from a “What Can I Do” context. It’s responsible, it puts matters in your own hands, and it allows you to be the driver of your own life, instead of a passenger.
