I'm a 19 year old female at university who made a really dumb decision.
In late January I had unprotected, drunken sex with a boy who's had multiple sexual partners (around 9 other girls). He was my first penetrative sex but due to his past I was instantly worried about catching an sti/std.
I had some symptoms of a sti/std around a month after our encounter (urge to urinate, mild vaginal irritation) but put off going to the doctor, probably due to anxiety. However, in the last two months since then (its now may) i've had loose stool movements, digestive issues and a lack of appetite. I've also had a swollen gland in my neck that seems to have stopped lately but it was pretty recurrent from early feb to early march.
I finally went to the doctor a couple of days ago after some pain in my lower abdomen and lower back pain which convinced me I had an sti/std. He put me on two lots of antibiotics to clear an infection if i do have one, which wont be confirmed for a couple of weeks.
However, throughout all of this I have had really intense anxiety, even convincing myself I have HIV which I still think about multiple times a day. I've also thought perhaps I am giving myself IBS from the high levels of stress and worrying and thats the cause of the diarrhea and no appetite.
Anyway, any advice or diagnostic advice would be greatly appreciated.
Is it really possible to make yourself this physically ill from anxiety? Being on the antibiotics is bringing a bit of relief as if i do have an infection at least i know its clearing it up now.
