It sounds like you are aware that anxiety is impacting your ability to be logical and reasonable about this situation. This forum is moderated which means that the information given is directed by physicians who specialize in HIV to make sure the information is accurate. You were accurately told that you had no risk for HIV when you used a condom. When condoms break, it is not something you are 'unsure' about. You would know. It's safe to conclude that you are right, anxiety is causing you a lot of undue worry. You should feel confident that you did not get HIV from your exposure but what are you going to do about the REAL issue? That anxiety needs to be addressed. What is the healthcare system for mental health like where you are located? Anxiety is treatable and I'd work with your doctor to start that kind of care.
The first step to peace is to stop Googling hiv cold turkey. The second is to stop examining your body looking for hiv symptoms cold turkey.
Until you do that, your mind will be in turmoil and you will do irrational things like 2 hours ago posting the same question that you asked yesterday, even though the science is 40 years old and didn't change overnight.
