Once you do that, imagine a gold fence all around your energy field. If you have to make it higher or thicker, do that. Go with your intuition for what you need. Then, when you are talking to someone who is pushing against your “no,” picture that fence between you as you say, “No, I can’t.” When you leave them, imagine the fence exploding. This allows their energy to go back to them and yours to come back to you.
