If you have this level of anxiety and you're working in a lab that includes blood samples, you need to talk to a doctor about addressing your anxiety. This is a no-risk event.
When it comes to blood, unless you are using a pre-used intravenous needle to inject yourself, into your vein, you aren't at risk for HIV.
Your lab has protocols for this kind of situation, but you didn't have any hiv risk. hiv is fragile and dead in air so the worst that happened is dead hiv touched you.
