What would cause my car to not start

What is your question?

I pulled into the gas station put car in park and turned the ignition off but when I shut it off it sounded a little rough then when I went to start it back up it didn't turn over at all and didn't get any sound from the starter only thing I could here was a little click

What makes this problem better or worse?

N/a

How long has your 1993 Nissan Altima had this problem?

First time I've had it and can't fix it
