would welcome an old friend, it will lose its power on you. Say something like, hello, old friend, you are here again, feel free to stay around but I have made a decision not to entertain you. And having said this, the old friend will slowly go away as if you do not keep talking to him he will leave eventually. Please take note that when we are resisting, pushing away the thoughts, avoiding and etc, we are actually giving the thoughts a lot of power as the more you resist, the more they will persist! Try this! close your eyes and tell yourself not to think of a lemon! You will realize that the more you resist the lemon, the more you will think of the lemon! This is exactly the same situation here!
