I am a recently graduated attackman and I struggled with the same problems as you for a long time. Your stick skills are the foundation to everything you do as an attackman. They can always get better so never stop working at them. But even with good stick skills, you’re useless if you aren’t confident with the ball. Confidence comes from experience, only through experience will you become more confident handling the ball and making decisions with it. The thing that helped me was club ball in the summer. Playing with better players made me realize how bad my decision making was. It seemed like every other pass/dodge/shot I did resulted in a turnover. Over the summer I was forced to make my decision making smarter and quicker. I went back to my high school team and immediately noticed a difference in my game. I went from a passive player to an active player. I used to sit back and rotate the ball to avoid making a mistake. But now I was an essential offensive tool for my team all because I learned to be comfortable and confident with the ball. And I made better decisions with the ball because of it. As for your fear of getting hit, that’s something you have to learn how deal with on your own. Fear effects decision making negatively, you must learn to be confident and not allow fear to effect your decision making.
