I'm making myself crazy

I got myself in a situation and I can't stop thinking of what I may have done to myself.   I know I need to just go see my doctor but I can't go till next week and in the meantime I've tried to just research online when,  how,  etc and I'm going crazy.  Do you realize almost every disease begins with flu like symptoms?

I met a guy and went out a few times.  Things got escalated,  and although we didn't have a condom and didn't have full penetration sexual contact we were close,  he did ejaculate but into a towel right away and wiped it all off him,  prior to that he may have rubbed up against me but never really getting fully inside me.  I think there is some risk but it's only been about a week, it doesn't seem like the timing is right to get tested.  I am so stupid and wasn't thinking.   This man is from another country,  I didn't ask that many questions before all this happened,  I'm worried since I have no idea of his hiv status and while I regularly get tested you never really know about anyone but yourself. 

I've been sick for a week or so and it just seems different,  I'm used to not feeling well because I have very severe allergies that are difficult to manage due to my other autoimmune problems but I know symptoms don't diagnose hiv, I need to be tested but what do I do in the meantime?  What are important things to ask my doctor to make sure there is a risk?

I'm very stressed my anxiety is worse than ever.   I just wish I could die right now.   I can't believe I was so stupid.
