I've snorkeled before and loved it. I tried snuba to see if I liked that....and I did, so scuba lessons seemed the next step. I liked the instructor during the first lesson, two days ago we had our first pool lesson with just snorkel gear and now I'm feeling extremely apprehensive. I don't have a problem breathing underwater, or clearing my mask underwater, or using fins, etc., but I sensed the instructor thinks I will have a problem tomorrow when we use the scuba gear for the first time. I told him after the first pool session that I think I need to get a wetsuit because I was shivering at the end and he suggested I wait to "see how it goes" tomorrow. I'd like someone to give me some encouragement that this isn't going to be a problem because I was really looking forward to this new experience and now I'm very uncomfortable. Any help greatly appreciated!!
