Does your condition require immediate assistance? Does your mother or father hold any privileges (regular pioneer, ministerial servant or elder)? If so, I would advise calling the local body of elder of their congregation and letting them know about your situation; than ask them if they endorse this type of response... If they do not, they should counsel (even discipline) your parents. If they do nothing about it, politely tell them that you will contact the local branch.
They probably won't want that type of heat and will give a "pass" to your parents who will be happy to help you. If your parents are not happy about that.. then sorry, sometimes, people don't need religion to stop loving their own children. Sometimes, they actually use religion as an excuse for becoming self obsessed.
