What should I do knowing that my parents have copies of my personal ID & some financial statements?

I discovered that my parents have images of my driver's licence, centrelink card, centrelink statement of payments, & a copy of a credit card debt statement, on their computer. I am 48 years of age, they are in their late 70's & have given me 30 years of disrespect with one thing and another, to which I have been continually perplexed about & saddened by. I am fed up with their disrespect towards me & my son, & have decided that the only road to take now is to break all communication with them. They have obtained my personal details & photo copied my ID! What should I do?
