AIO ? Health scare- positive HIV exposure

I am a bit of a hypochondriac, but I fear my biggest fears have came true. I am still freaking out. For context this is a post from earlier;

I had posted my story earlier this week. I had one occurrence of unprotected receptive vaginal sex with a male friend (I don’t know his status). It was brief, not rough but there was some pre cum and maybe some semen a small amount though, that went in. I took a plan b right afterwards. He is saying he’s clean I am just not sure and I dont know why I did this to myself. He is a straight 22 year old from Brooklyn and I am a 20 year old. I am horrified i’m usually so careful about this stuff. I don’t know how I let this happen. He was my second partner ever so if this really happens and I test positive my luck is horrible and the universe wants me gone. The sexual encounter happened September 1st, now it is September 11th, I’m feeling a bit of a headache, runny/stuffed nose and my sore throat is now gone. I’m horrified and my fourth generation HIV blood test isn’t until October 16 (to be sure it’s after the window period) I don’t know if the anxiety will let me make it to that date. I’m almost considering suicide.

Update;

Im still feeling some symptoms, when I let out a cough it's one of those dry hollow types of coughs with some echoing. There is some diarrhea, not too sure about a fever or fatigue. I have fully accepted that I have contracted it at this point, I have all the symptoms of acute hiv infection. I am feeling pure impending doom.
