I have always used the old rubber band around the wrist trick (snap the band on the inner wrist every time you have an unwanted or intrusive thought) - then replace the thought with a positive one.

Shaking ones head as to say no is also another way to remove the thought ASAP!
... you can say NO out loud if you need.

((((Babysteps09)))) Mybe try to remember how wonderful you are. When your darkest thoughts creep up on you. Remember ( I am a wonderful ). I can do this.

I thank you for all of the support you have given me.
