This can mean a many of things, this falls under my category of bullying, harassing etc Knowing someone is attacking you and you have no idea why apply this message to oneself. This behavior could be on the job, church, relationships, organizations, etc.
However, it may look as the other person is winning sit back and do absolutely nothing. This is very hard we as humans tend to want to defend ourselves when we feel as though we are being attacked. I have experienced myself, someone, what we call (coming for you) meaning attacking or harassing in any form and you did not send for them. Having this knowledge when I was younger sure would have saved me a lot of heartaches.
Moving forward in my day I will not put any energy into a lost soul all that will do is give me a stroke. By attempting to destroy someone in the process you are bringing attention to yourself. Non the less this is about how to move on from whatever your situation you are in.
If this is your current situation ask yourself spending all the time reporting, writing down everything that is a lot of energy. However, the energy you are using is it towards your goal?
Let us not get distracted by something that is out of our control.
