Severe anxiety after night out

[Waony]

Hello, I am currently experiencing a severe episode of anxiety and not even eating.  I was out at a bar with a friend about 2 weeks ago.   My friend left before me and I ended up staying until after midnight and I drank too much which was irresponsible of me.  In my drunk state I had a brief chat with a girl who also turned out to be a sex worker.  I remember buying her a drink and intentionally walking away as I was not looking for that.  I am very risk averse when it comes to sexual matters and I am faithful my girlfriend.  I continued drinking alone.

I ended up getting drunk to the point where I cannot remember some things about the night including my journey home.  I worry about whether I had any other interaction with that girl which I do not remember.  I have tried to reconstruct the parts of the night which I do not remember to ease my anxiety .  I have viewed CCTV footage at my house which shows that I arrived home alone.  I was so worried that I also went back to the bar where I was and asked the security team to help me by confirming what time I left and whether I was alone.  Although they did not show me the footage due to their policy (they say they only show footage if there is a police report) they informed me verbally that they checked and their footage shows me leaving and driving off alone. My mind keeps telling me maybe they mistook me for someone else.

Normally the drive home takes no more than 30mins but I arrived home after about 1hour and 10 mins that morning judging from the time I was told I left the bar and the time stamp on the CCTV footage at the house.  I keep wondering why it took me so long and by any chance if I was with that girl.  I would like to believe it took me a while to get home because I got lost several times in my drunk state however I cannot stop worrying about whether I could be wrong about this.

I have no evidence of sexual activity from that night but I am so worried about hiv and constantly wondering if anything happened with her since I cannot recall everything and there is time I am unable to account for. I keep worrying that maybe I was with her and later deopped her off before getting home.

I can't stop worrying
