it sounds like you are in a very bad situation for a weed smoker ..most parents who send thier kids to a christian school.. are not going to understand that they have been lied to by the media and the govt about marijuana.. and the kids are going to be the same way..... but i would keep doing what you said about not keeping your stash in the house.... and if you get caught just tell them you were curious and wanted to try it.... and now you know so you wont do it again .. you will need to be carful until you are old enough to move out on your own..because fighting with your folks over weed use by a minor wont work .. but it's no reason to avoid your family so id say just bite the bullet till you can get out on your own good luck dude
