Soccer veteran... Come back?

I used to pay soccer when I was six until I was about 8, now, about 4 years later, I think I want to play again. I'm sort of good, my friends and family say I'm a strong player. A friend who plays on the team says they're not very good and I would be one of the better players. I also play hockey and lacrosse, which help my skills a little. But I'm scared I'm going to go in there and make a huge mistake. Fall on my , make a goal for the other team, or something that would definitely humiliate me. So should I join, or just stick to my other sports?
