Stress or AIDS ?

I had an 'encounter' about 3-4 weeks ago. About 3-4 days after, I started to have a pain on the left side of my groin. I then went on vacation, and the pain was there for majority of the trip. I first thought It was due to my unhealthy eating and not being able to go to the bathroom. (after I ate some healthy stuff and went, the pain slowly disapeared) When I got home I looked up what could of sparked the pain in the left side of the groin. and I came apon a site saying it could be that start of HIV/AIDS. Right after I read this my stomach turned, and I started having panic attacks and anxiety attacks. Now I feel like I have all the symptoms. I dont know which are from stress and anixety or if it could actaully be HIV. Most of the symptoms are like nausea, fatigue, nightmares, sweating, shaking, tingling, chest pains, trouble breathing ect. I also saw how aids can cause thrush on tongue, and I had white on my tounge. (BUT.. ive always been a poor brusher, and have had a lot of plaque on my tounge) Ive also been worrying my self to not cough, or even feel a slight flu like symptom, and now It feels like htere is one coming on.

Does HIV work that fast? Any help would be greatful, thank you.
