Narrative:

Taxiing from parking space below tower, contacted ground and received clearance to cross runway 19R hold short runway 19L. Called tower 2 times, said I was holding short of runway 19L and requested to go FBO east. Some other person kept stepping on my transmission, so I wasn't aware if they knew I was holding short runway 19R. Ground gave clearance to cross runway 19R to FBO. I called tower and said, was that transmission for me? Ground said go, and they knew where I was and that I was in a confused state. Transmission being stepped on, I proceed to cross to taxiway C, I saw the taxiway C sign and mistook the runway 19L for taxiway C. Once on runway and see my mistake, I exit the runway as soon as possible. Once at FBO I was informed to call the tower, which I did, and was told what I had done, and asked why? I told them I was a student and I got confused with all the action and people talking all at once. The tower at the time didn't know I was student. I had never taxied my aircraft alone before. Did I learn anything from this? I said, yes and understand how this could have been. It did happen and I will listen and follow instructions. Look before moving. Make sure where I am going. Where I'm at. Who's talking to who!
