I already did assume the best of the OP: I assumed that they simply do not grasp how unproductive and, frankly, stupid their choices are, rather than that they are making them out of pure carelessness or outright malice. They made it clear that they would prefer to simply blow off therapy and instead self-medicate using unprescribed drugs, underage, which will stunt their neurological and psychological development and simultaneously present a significantly higher risk of psychological addiction. It's a stupid decision and I am not ashamed to treat it as such.

As to the other circumstances, we are simply not going to agree, unless the OP provides more information. That's fine.
