I'm sorry your going through such a hard time. My advice is to reproach your parents and re phase what your telling them. Saying you have parasites sounds crazy. When I tell my friends and family about this they look at me like I'm nuts. Maybe tell them you did some research and want to try a holistic approach to cure yourself. In the mean time I found this website that has foods you can use around the house to get rid of these http://www.findhomeremedy.com/15-natural-cures-for-parasites-in-the-intestine/
