That does indeed sound unhealthy and more like a cult. Strangely enough, it also reminds me a little of American companies, the brainwashing and then that weird thing about not being allowed to tell your parents. For me, that would be a good reason to tell my parents, hahaha. They still have a lot to learn because if you tell people they can't do something when they can, if you think what you're doing is perfectly normal, you're not even going to make that comment, so I don't think it's very smart.
And how strange that you have to swear, I wouldn't do that at all. Even with my fingers crossed behind my back, I kept my mouth shut.

When you really have a dream, no one can kill it. Hold on to your dream, or you're vain, and see this as a stopover at most and study how people react and how they manipulate. When you view everything from a distance, as if it were one big play, which of course this nonsense is, it affects you less and you don't lose your mind or your dreams. Focus on what you do enjoy and the rest is a stopover. Try to find a healthier environment as soon as possible. I wish you the best of luck.
