Hello , I am a student Pilot.
Yesterday I did two landings with my instructor, then he proceeded to taxi to the pumps to let me loose on my own. As I took off and climbed upwind, turbulence got worse. got to finals, then went around because there was an aircraft on the runway still at 300'.
On final again, went around about 400' because there was an aircraft on the runway and turbulence was bad and my profile was not good, I banged my head on the ceiling causing me to go dizzy. I called going around, and the tower said "is there a problem?" I said "aircraft on the runway", to which I was told "you could have made it you had 1/4 mile".
I thought to myself "this is too rough for me" so I called downwind to land.
Tower then rang my school and apparently asked if I was nervous!
What did I do wrong here?
Help.
