I got really drunk last night and I spent half an hour in the dirtiest toilet because I felt sick. I didn't care at the time. I'm nit sure if my mouth hit the toilets but when I wiped my mouth this morning there was red stuff, I'm sure there was no blood there, I could have been vomit though or maybe salsa sauce. I'm worried about hiv or herpes, I'm too scared to get checked. Am I overreacting?
