Who in your sphere of influence is toxic to you? We all have experienced those people, who as soon as they walk in a room, the energy gets dark. Do you know what I'm talking about?
I had people like this in my life and it took me a long time to recognize the effect it was having on me. At first blush, you can tell yourself that it doesn't matter how they are, but it does! Energy permeates even the tiniest crevices and that includes our thoughts, emotions, and even our physical being.
If this is something you have not already addressed in your life, start taking notice of how you feel when certain people are around you. Do they make you smile and lift you up? If not, then how do they make you feel? How does the space you are both in feel? Do other people make a hasty exit when they get there? All these questions will become second nature to you when you start to pay attention and make changes.
It is easy to advise someone to leave an abusive relationship, or to spot a person who has let themselves fall into a life of lack. But it is not always so easy to see the people who look nice and appear to be nice, when in fact; they are not looking out for the best interest of those around them. Pay attention and see what you come up with.
