I am sorry you are so scared, but please - suicide is never the right answer. I hope you can talk to a counselor about your feelings.
First, you did have a risk, and the good news is that you can - and should - test at any time now for a conclusive result. Knowing the truth, one way or the other, will allow you to take action and move forward. If you don't test, you will be stuck in this misery until you do.
Second, your symptoms do not sound like HIV. You would never get symptoms 2 days after the event. If you got hives 2 days later, it isn't HIV-related. Also, hives are usually itchy, and a rash related to HIV is not.
Also, the symptoms would not endure through the 12th week.
Having said all of that, HIV is NEVER diagnosed by symptoms or lack of symptoms. It is diagnosed exclusively by testing for HIV. Please take a test as soon as you can, and please come back to tell us your result. Regardless of your risk, HIV is not that easy to contract, and your chances of getting a negative result are WAY higher than getting a positive result.
I forgot to mention I had pink eye and the hives started 2 days after the exposure. It was unprotected vaginal sex. Should i get tested.?
