STARTING OVER FOR THE ( I CAN'T COUNT THAT HIGH ) TIME!!

Ok, here I am again starting over. When I started working on my weight in 2007 I started at 368 pounds. I lost over 100 pounds stating that I would never go back to the way I was, eating, not working out and gaining weight. Well here I am at 331! I know I have to do this, yesterday I checked my blood pressure and if I had been at my doctors office I know he would have put me back on my meds after 3 years. I do not feel well, I am tired all of the time and very moody. I know this is hard but I know that I have to do this AGAIN. Today we started a new challenge on a team, to stay on our own program. Well I did go over my calorie range by 122 calories, but I haven't even tracked any of my food intake for an entire day for most if not all of the month of October, so I think it's a good start. I do have in 8 cups of water and yes I did get in 30 minutes on the treadmill. Here again I was disappointed with my workout. It took me 30 minutes to walk 1.25 miles when a year ago I could do 2 miles in 40 minutes.
I have to stop thinking of what I could do a year ago and concentrate on working on today. Last year, last month, last week and yesterday are in the past. I have to focus on today and today only. If I go over my range by a small amount ( stay under 2000 cals per day ) and if I get in at least 30 minutes of fitness a day no matter the mileage that is a good thing. I will learn to say "You have done an excellent job and keep it up" to myself.
I read a sentence I have written down so that I can see it at anytime. It is: My time and energy are to precious to spend on stress. I am not going to stress over not being "perfect". That is ok, I am not perfect, just working on getting better.
