I can understand how difficult and scary it must be for you to think about the possibility of getting infected with HIV. I also understand that due to the fear, you find yourself searching for its symptoms and feel that you have had all the symptoms.
Often, it happens that we search and read about a certain disease or an illness because of our fear of the possibility of having it. What we don't realize is that the more we read about it, the more we will feel we have it. Here, what we are doing is assuming on the possibility. And it is the assumption which leads to more fear and anxiety. Although there is a possibility it can be confirmed only by a standardized test. Just because you have a few similar HIV related symptoms does not mean that you have HIV until and unless the test confirms it.
Another thing is there is a lot of misconception about certain diseases. Having infected with HIV does not mean that life ends there. There are many successful people living with HIV.
Getting tested is the only way to confirm whether you have HIV or not rather than based on assumption. Because fear is always worse than the reality.
