well I've been in your place though in my case it was my parents religion I ran away aswell and think calmed down for a while aswell then back to how they were I mean I think your parents just want you to be safe and stuff there is a lot of sh..t out there but I think they need to learn how to aproach it and realize what u r gonna do u r gonna do behind their back if they forbid it and see that what they need to do is communicate with you and let you know of the dangers not try and keep you from them I suggest you talk to them I don't know how old u r u sound ummm 16? cuz of the school grade but at 17 in some states you can move out don't get me wrong I don't think that is the answer but mayb letting your parents know then u will have the choice they will have to let go a lil trust me they don't want you to move out tell them u wanna stay at home but tell them how much their mistrust is f..cking you up make them listen to how its effecting you and why in what aspects and let them know u don't want to do n.e thing bad you just want to have some personal life say that them beeing so mistrusting makes you feel like u can't talk to them about your problems pr the issues at home w yer bf friends etc
good luck girl ..
