Choice of Power

For a long time i have let people around me and situations that i have no control over effect how i felt pretty severely. Lately that has especially included my step mother.
But i realised last night that when i cut because of things that she has said and done, i am giving her power over me and my life that i really dont want her to have. As much as i am used to SI, and as much as it feels like it is my oldest, and sometimes my only friend, i would prefer to try to live without it than to let her have that sort of power over me. There is no way that i am going to live with her having that sort of power over me, know that i can recognise that it is there!
Because of this, i have decided (again) that i am not going to SI anymore. I did decide this before, but at that time i decided it for other people, but this time i am going to do it for myself. I know that it will be hard, but i am determined to stick with it. If i stumble (and i know i will), i will get back up and keep going again.
