Finding out that you are infected is usually overwhelming. Even if you had suspected it for some time, learning that you are can be a very traumatic (令人痛苦的) experience. Testing HIV positive has led some people to quit their jobs, quickly write out their wills, and say goodbye to their friends and family, only to discover that they aren't sick and will probably live fur many years to come. It's common to perceive these results as an immediate death sentence, but this is simply not true. What you are feeling now is perfectly normal. Anger, fear, confusion, numbness, depression all are completely natural reactions to the kind of news you've heard. If you've known fur even several weeks, you may find yourself having a normal day, then suddenly remember that you are HIV positive. It's very common for this kind of realization to just 'hit you in the face' out of nowhere over again. You are not going crazy if this happens to you. Your moods may swing from profound sadness one moment to extreme anger the next. That's normal, too. The first step to get through this emotional turmoil (混乱) is to acknowledge what you are feeling. Don't be surprised to find yourself going through the day in a state of shock. Allow yourself to feel nothing. Your emotions will come rushing back in soon enough. This is merely a way that your mind 'turns off' to allow you to cope with a problem, If you are feeling angry, that's fine. You have every right to be angry and a lot to be angry about. This virus is threatening your very existence. It's okay to express this anger. If you're frightened, acknowledge your fears. You are thinking about things that would make anyone fearful. You are allowed to feel the way you do. Don't be hard on yourself or think you have to be strong. You don't have to be anything. What does the author mean by saying 'learning that you are' (Line 2, Para. 1)?
