Having weird symptoms?

Over the past week Ive been sick. At first I was just very tired, all week, and then i got a really bad cough. Not a dry cough, like coughing up phlegm, and then later i felt a little light headed, and nauseous. Then the next day, I was sitting around, and I started to get palpitations, like my heart was racing, and I felt like I had a lump in my throat. My eyes were also pretty bloodshot. In 15, 20 minutes or so I felt fine, but still sick. I'm 13, and I take adderall if that changes anything. Anyone know what i'm sick with?
