Sadly I think there are a lot of childish adults, but worse, adults who don't honour their children as sentient beings. I'm 56 and actually remember being your age. I believe you sound incredibly smart and well mannered. You strike me as a young woman who has a head on her shoulders and can be trusted with adult conversations and concepts. People too often dismiss lack of experience for inability to fathom and process simple/complex situations, which is so clearly wrong in your case. I am sorry you are stuck there for another year and a half.
