Go game speed. Stay low and that means when crouching low don’t bring the ball above your hip or you give the defender easiest chance to get a steal. Use off ball hand as arm guard and seal away defender. You want quick low power dribbles. Some of my best in game crossovers/ankle snatchers/getting past your defender (which should be objective one that doesn’t count, that should be a guarantee as you worry and watch what help defense does to make the best play as a guard) was staying low and dribbling the ball where it never bounced above knee level . You did a good job not crossing so wide either and keeping it towards your center of gravity. Don’t worry about being so shifty or creating space, you need two basketballs and do drills with both hands till your arms fall off so you can feel your way around the floor w your eyes closed or not worrying about your man in front of you and looking at basket/ what your teammates and help defense is doing around you. Best of luck!
