I went to a fortune teller 5 years ago and I believed in all the things she told me now I want to repent for believing in fortune telling. I know what I need to do to repent, regret it, try to not do it again and in my case also I must not believe anything she said, this is where the problem comes. now (5 years on) I can only remember some of the things she told me, I have forgotten the rest. I remember after I visited her I went home and wrote down everything she told me in a book, I still have the book. if I look in it now I will be able to recall all the things she said to me (including the ones I forgot). I was so ready to repent, I had deep regret in my heart, I was determined to never commit this mistake again and anything which I do remember she told me I completely disbelieve in them now then this person came and confused me. he said my tauba will only be valid if I disbelieve in EVERYTHING she told me, I can’t because I have forgotten most of it, he then said I have to look in my book (which contains everything she said to me) and I have to disbelieve in all of them only then will my tauba be valid. is he correct? anything which I do remember I disbelieve in should I just ignore him and repent or is he right do I need to disbelieve in all that she told me in order for my tauba to be valid. this man really confused me please tell me what to do I just want to repent
