Why don't i feel good?! I'm tired of feeling bad

Okay so, Monday 6th, I came down with a virus of some sort. High fever, extreme body aches, headaches, runny stuffy nose, cough... Etc just normal sick symptoms. It took a full week for my fever to go down an to not be sick anymore. I'm feeling better. Just still have a horrible cough. Tuesday I was in a BAD mood most of the day, and the same with Wednesday. I just all around was in a bad mood an didn't feel good. An I started my period yesterday morning too... Why don't I feel good? Today I feel awful an just off. Besides my period side effects. Why am I having all these other issues..? I am so tired of not feeling good right now :( any suggestions as to why? Or suggestions on how to make me feel better? I just feel like I'm in a fog... Any thoughts ladies?
