cycling and the flu

I am in the middle of my 6th week of test and eq and for almost the past week I have been sick, and on top of that i was sick about a week ago for a few days with almost the same thing. Im always tired and have no energy, I can never eat or even wake up in the morning and all i do is cough and sneeze. Can eq be causing this and if so, whats the longest yall have had a flu while on cycle? This is really pissing me off cause i am up 10 lbs and im slowly starting to lose it because i just cant eat like i was and i just dont have the energy to go to the gym or work out my hardest.
