I always think the worst of things

As the cold seasons are beginning, I become sick. So I start googling my symptoms and it seems like I have flu symptoms. I stumble across something that said you might experience flue symptoms from HIV EXPOSURE. So now I'm panicking, questioning my whole life. Like yes I've had unprotected sex. Yes I'm questioning the worse. Never thought in a million years I'd feel like I need to get tested for HIV but scheduled to get tested.. Should I be worrying so badly?
