First tri coming fast- anxious, excited, nervous

hello everyone,
i am a newbie to the sport and decided in mid march that I needed a lifestyle change, I was stressed out, overweight, and generally uninspired. I had just moved with my wife and 1 1/2 year old away from my family and the beaches of florida to atlanta and just wasnt feelin' it. So my wife decided to train for a 5k and I said ok me too, then I decided to take it a step further-TRIATHLON. Well, 2.5 months later, 20 pounds lighter, and several miles and hours of training later I feel like a different person. I am once again confident, happy, and Have the enegy and motivation to be a better person in my job and at home. My first triathlon is in 3 weeks, I am still struggling a bit on the bike and not a very fast runner and still have 25 pounds to lose, but I KNOW I can finish. This spring has been a life changing adventure and I cant wait to see how far I can take it.
