Here is the real Shrink, Kiddo's advice: First it looks that you yourself aren't sure within if you want to get rid of her or not. You know it you do, So affirm yourself. Now, before going to bed, think of the nasty things she did. Do this for 5 straight nights. You will start hating her. This is called Shrink Kiddo's Sleep Therapy. What you are doing is you are strengthening your hate synopsis, neurologically. Also you are generating enough hate harmones for your subconscious mind. Try it, it will work.
