“Doctors & Nurses, What Sickness Is This? Is It HIV?”

The thing is: I’m scared shitless right now. For the past few months I’ve been having a monthly series of flu sickness. I mean every month for over 5months now. The one I’m currently experiencing now has just got me very much scared. Below are the things I’m experiencing now:
– Flu(whooping cough and catarrh)
– Sleepless nights
– Loss of appetite
– Weight loss
– Body vibration
– Tiredness
– Stooling (Diarrhea)
– Headache
– Fever
I’ve read about the fact that most of the above are possible symptoms of the hiv virus and anytime I think of the possibility of me being (i can’t even mention it) ,i just feel like dying. Yes I’ve been living a very promiscuous lifestyle and its more reason for me to be scared of doing a test. Although I’ve done it before in 2014 and it was negative but since then, there have been a lot of sexcapades. Which brings me to my question directed to doctors or health practitioners : "Is there any other sickness that can be related to those symptoms above apart from Hiv? "
To those with the virus already I’d like to ask: "Did you experience something like that before you were confirmed as positive? "
