Hi there. I'm a beginner learning to dive in the beautiful but frigid waters of Vancouver, Canada. I attempted to certify this weekend and couldn't, and I'm devestated. I'm about 5'7 and 110 pounds, and I'm wearing a neoprene drysuit, 36 pound weight belt, 20 pound tank, and about 10 pounds of other equipment. The problem is that by the time I get in the water, I'm so exhausted that I can't do any skills. I'm really frustrated and bitterly disappointed, and would love any advice anyone has to give, since I'm not ready to give up yet! Thank you!
