forget the past

still i cant either forget it nor deal with it ” my past” it is taking very large part in my thinkings why???
i think cause i see others not having the same past as i have and they dont feel me at all; most of them are succeeding and feeling the happiness of life while i am remembering the painful past and crying for the future
but this must be ended i want to end it ; it is interrupting my work and represents a rock in my way of acheiving my dreams
but how can i help myself without waiting for others to help me forget the past ????!!!

when i was young and my mother was telling me her story life; i was fabulous with her story and all what she passed through and i asked myself a question at that time ” what will i say to my daughter when i grow up about my life story?” (at that time i didnt have one and my life was fill of happiness and joy)
then it comes the story after two years and i pass the hardest story of my life with my mother to be the history of mine and the story that i will tell to my daughter one day to learn the experience
but now this past hurts me alot although i learned alot from it but it hurts me and i want also to take my revenge from the ones that shared in increasing the pain intending that they were helping me and after i depended on them they left me left me filled with pain and sorrow i dont know do i have to forget the past ?! or take from it the force to contue being strong?! i am really confused
