I can totally understand where you're coming from, rod. I myself recently have dealt with some issues that were bringing me down. Thankfully, my wife brought reality back to my attention. I can't tell you how much i needed that to refocus on my goals in life.
The support of others can definitely assist in getting over the funk stage. I know it's hard to break bad habits, especially when life has thrown you a curve ball, but there is light at the end of the tunnel. Your AM brethren are here to support and help you through this time buddy. Keep your head up, and take it oneday at a time. I know i am.
My new goals are to gain entrance into a Nurse Practitoner/Physician Assistant progam by fall of next year, and to achieve my best fitness physique by the end of 2009.
