Replying to Tell me if i am being paranoid

So I was going to smoke a bowl with my buddy, and we went to some ally on campus to do it. We see this spoon on the ground, and without thinking I pick it up, and it was a heroin cooking spoon, and I didnt realize until after picking it up that it was a really stupid call to do that because heroin users cook their heroin in there and then suck it up with their dirty needles which can have hepatitis, syphilis, or HIV. So, if I accidentally touched a scab or my eyes, or happened to open a beer can with my dirty fingers and drink from it before remembering to wash my hands (oops), there is a chance I could get sick. I know it isnt a big chance, but im still worried. Does NS think i should get tested or am I just paranoid?
