I seriously need opinions, please?

Hey, I've been "sick" lately just ears, headaches, throat and cough. I'm better but I always get headaches & I still have my cough. /: my cough is aggravating and jolts my whole body, and some reason tonight I felt like my heart was weak? But it beats big. Also I had like weird headaches on the top of my head. Idkk. Am I just a hypochondriac? Please help. Thanks thanks.
