trust me girl you are not stupid, it happens to the best of us, I have been riding for 20+ years and still drop my bike, once recently when the bike was turned off, sitting in the driveway.
What the others said is so true too. But before you get on the bike you may want to try a little visualization.
I had the same problem at the track, I kept running off the track in turn one, over and over and over. My instructor told me to stop thinking about the last time I came in too hot and grabbed too much front brake stood the bike up and ran off the track. He said instead visualize myself completing the turn the way I want to. Smooth on brakes, smooth down shift, smooth body position, a sane entry speed...ect that way when I come up to the turn, my mind, body and bike are all going to do what I want them to do. He made me sit there and visualize this over and over and over. Once I got back on the track, I was not thinking about running off the track, I was doing all the things I had thought about. It helps me both on and off the track.
