Im 17 I have no money 
Oh, man, Ive been reading depressing reddit stories for several hours now and somehow this hits hard. My advice is this dude, if you dont have money to treat urself in emergency case, forget it. Nothing, literally nothing is worth the insury you can cause urself. But then again, I dont know much about NCR, you have probably read about the several people here in the forum doing it. Think hard about it, all I can say and I apologise for not being able to give u answer to ur question.
