The source of our unhappiness is not outside us.
It could be said, that we are being irresponsible when we blame others for our unhappiness. So often we say things like "She makes me so mad," or "He makes me feel worthless," but no one makes us anything. The most anyone can do is point to the parts of ourselves we're not honoring, by mirroring back to us our own insecurity or self-criticism. Blaming others for this reflection is like blaming our bathroom mirror when we look into it and don't like what we see. That's pretty silly, right?
If we find ourselves in a position where we're not cherished, it's up to us to get out. Staying in an unhealthy situation or one that doesn't resonate with us, then blaming outward for how we feel while we're there, is playing victim. No one is responsible for our happiness. That's our gig. Blaming someone else for our displeasure means we're making them responsible for our experience. This type of finger pointing could signal that we're not standing in our power, but instead willfully hand it over to others, then blame them for our misery when they mismanage it.
Standing in our power means being courageous enough to stand up for our ourselves and our values, while taking full responsibility for our lives. No more blame. Blame is a way to evade looking at ourselves and dealing with whatever is going on within us. It is avoidance. It is an attempt to make someone else a scapegoat for how we feel.
We choose our actions, or inactions.
Our feelings of unworthiness are our own. Our anger is on us.
Not being happy is our responsibility to rectify.
