Still Discouraged

Ok, so yesterday morning, I rode my bike for an hour from 5am to 6am.  I was supposed to do it for two hours, but I freaked myself out because it was so dark out and South Florida drivers are nortorious for hitting cyclists and not caring that we have a right to be on the road too.  I am getting discouraged because life is getting in the way of my training.  I got at least an hour to 2 hours a day in, but can't seem to get all the hours in necessary.  I am also discouraged because I slept through the FAU tri, I had no desire to do it this morning, I was so tired but I did get a good 45 minute spin class in (without an instructor, who didn't show up.) and I am discouraged because the weight is not coming off.  I only cheat one day a week (usually Saturdays,) and am careful about what I eat and nothing is working.  I am either too hungry and ignore it or I  stuff myself at night or just get pissed and eat. GRR!! ;-).  This coming week I only have to do twelve hours of working out and have nothing planned to stop me.  I am also really confused about how to train for the nutrition aspect of the race and haven't really done it.  Any suggestions? (Thanks, kerry, for the website, that has also helped), but I need more.
On a brighter note, I swam in a meet and was actually happy with my times, considering I am not focusing on swimming, I am focusing much  more on running/cycling.  The running, by the way, comes much easier to others than me and it makes me mad that I can't run more than  6 miles right now.  I have been doing this forever!  Ok, I was side-tracked, but yesterday was nice and it ended on a really bright note with Bryan's 31st birthday dinner.  It was nice to be surrounded by friends.  Off to the Bon Jovi concert tonight.
