For 12 years I've been living in fear of having hiv and haven't slept with anyone since I potentially was exposed. My question is, would I likely know (ie- have fallen quite ill by now) if I had contracted it 12, maybe 12.5 years ago?
Not necessarily.Some people go 10,20,30 years before ever feeling ill.Some people never get sick at all. You may not have HIV and then what?You have wasted all this time.
You should get tested.Not knowing is far worse than knowing and taking action. Its not so scary once you know. Start living again and get tested.
