Did I get AIDS?

Good day,

The question sounds stupid, yeah, but I'm a bit of a hypochondriac, so I have to ask it. I was in a techno club with friends yesterday, and when we went to the McCes afterwards, they noticed that I had a small cut, or rather two next to each other, because I'd been bleeding a bit. I probably didn't notice because I'd had a bit of alcohol. But in the club, we were asked five times if we had any molly or anything else or something to snort, and now I'm worried that I caught it there, because in scenes like that, well. Or that I touched a needle somewhere. It's unlikely, but I'm just so panicked.
