So much to do at that age. You should be too busy to deal with this nonsense. He may get use to you not around and go bother somebody else. Now is the time to get busy with school and/or a trade. Get some work/real world experience. Take care of yourself physically, join a gym, take up some kind of running or biking or swimming. If things go well you're gonna be stuck with that body for a long time. Get rid of those cigarettes! Not sure if you're old enough to vape where you live, its 21 some places. Your old enough to drive or go to war, but OMG, vape, NOOOO! That would get your nic fix with less damage, less money, wont stink up the house as bad or as permanent. Just use a real vape shop and not some garbage liquid, if/when you're old enough.
