Are you voluntary? If not then you still have rights - i'd demand advocacy and make sure there's an outside body looking out for you. No one should feel harassed regardless of whatever's wrong with them. Can you get a copy of your treatment plan to see if there are any explanations as to why the staff are treating you this way? It could well be part of the treatment though this should have been explicitly discussed. Other than that i would recommend speaking to the head honcho there and demanding an explanation or threaten legal action. You're not being help captive you have a right to know what's going on and why. If all else fails surely you can request to be transferred somewhere else? Sorry is this is all very obvious logical advice but the only way to fight the system - is to fight it. Good luck.
