Hi LisaMarie,
Remember you have only been doing this for a short time, and it will get easier in time. I think it is good not to get too dependent on a choreographed routine. My instructor doesn't believe in teaching set routines, although in the beginning I begged him otherwise, so I had to learn to follow. I kept wanting to anticipate the steps. He always tells me that if I anticipate and make a choice without following his lead, nine times out of ten I will make the wrong choice and get myself into trouble. So I had to learn to be patient and follow. It takes waiting that extra split second to read his lead, and not being so quick to guess what he's going to do.
Maybe you could ask your instructor to slowly go over the step, giving you a "clue" to help you understand his lead. I'll ask my instructor "how do I know you are going to do such and such a step" and he'll tell me things like "I'll start with a cross body lead" or "I'll turn your hand" or "it starts with an underarm turn, or "I'll position you like so......" And then we'll do it slowly a few times, with him pointing out to me the signals he wants me to be aware of. This helped me become more aware of his clues and feel more comfortable. And he would spend time explaining why he was doing what he was doing. It was awkward at first and I felt very stupid, but I've never danced before and realized that if I was going have fun ballroom dancing I had to get over it. It comes much easier now, and I will dance with other men at the studio parties to practice how to follow.
By the way how did your first competition go? I hope you had a lot of fun!
