story is my mother left the family twenty+years ago to be with her lover .it left us as a family in bits me on medication and counselling whilst i was holding the rest of the family together. my elder sister let rip with a load of vitriol and decided to follow my mother so again have not seen her for twenty +years. anyway have not heard from the both of them for that amount of time until this christmas when my mother basically let rip saying that i have denied her from seeing my kids and asking if they (the kids) know anything of them .my mother also has stated that i should get back in contact with my sister . PLEASE HELP
