It's something like :I am not leaving calm. It's something like you are leaving a place where somebody told you a bad new and then you say that you are not going to be calm.
No....to mean 'I am not going to be calm', there should be the verb, 'estar'.
Or it sounds like you have been asked to leave a bar/party (or be thrown out) and you reply "I'm not leaving quietly". (Try and throw me out!).
No voy a estar tranquila. I am not going to be calm/content.
