You didn't have a risk and that should make you relieved and happy to hear this news. But instead you're on here wasting your time trying to prove anyone wrong who just gave you this great news. Why are you doing this? That is not normal behavior. Instead that is what someone with an irrational obsession does, which is why you need to get therapy for your problem. No one here can help you with this.
You are worrying yourself to death. You have 49 posts about a disease that you do not have, so you should consider how much of your life has and is being wasted every day fixating on hiv. There are 5,000 diseases that any person can acquire, so there is no reason for you to focus on the one that you can't have!
Anyone can find a new job so no one here cares why they left. This is an hiv forum and you don't have hiv, so you should ask questions about their careers directly to them. But if you do call them, no one here needs an update.
