It appears that you pushed your handlebars up AND pushed your seat way down. You seat height should be such that you still have a slight bend in your leg when at the bottom of the stroke. Don't expect to reach the ground from the saddle unless well up on the balls of your feet. The proper way to stop is to dismount from the saddle. Because of the angle I can't tell what you did to raise the stem, but it's important to remember that one adjusts the reach (distance forward) of the stem before height.
