I’m not sure what I have, STD , HIV? Please help!

Patient: Hi! About 2 days ago, I’ve received oral sex from a girl for like a good 50 seconds and then I was finished. I asked prior to the girl if she was clean, and she replied “Yes.” But, on the way back, I was super duper stress and I felt like my life was over. The next morning, I got these rashes on my arm, and little on my thighs. I did go to my friends house and I’m allergic to cats but that was some days ago. Next day I take these hive pills, and I’ve got the white little spots on my lips. Like a burning sensation, but I can’t seem to feel the lumps at all, they look like hives. I have been REALLY stressed this week, could it be from stress? I feel like my life’s over : ( Could it be hiv? or std?PLEASE HELP ME…!
