You will have to get your mindset right to escape this hospital and be free again. There has been a mistake, but they are denying this mistake and refusing to get you out. So, what you need is to protect yourself at all costs and attack the right people with the right force. You have a very good plan in your mind, but it may be a little hard to prosecute that plan. So, use the chances at hand wisely and make use of the objects you collect. You will unlock many doors, attack some doctors, and go through a lot of things.
