I know you're in a horrible situation right now, but take some deep breaths and keep telling yourself that you will be OK, and that it will pass.
Is the mental health team visiting tomorrow? If they are, then I think it would be a really good idea to tell them how you have been feeling. You had said earlier today that you felt the Sertraline was helping you to feel calmer, and you certainly sounded much more positive. It might be that the dose you are on needs to be increased, or that you just need to give it a bit more time.
