Don't beat yourself up. It was a birthday and you celebrated! And it sounds like you did make some good choices- you gave half the nachos to your daughter (I know I'd prob would've had the whole thing)

Tomorrow is a new day. You don't have to let today affect it. Maybe do 10 extra min of exercise to balance out the cake if it's still on your mind. But keep moving forward!!!

You will have days like this. This is not the first, this will not be the last. Acknowlegde it and then move on. I was very sick all summer and most of fall and, even though I'm better, I've been using that as an excuse to not get out and exercise or count my calories. I'm sick again but I WILL be starting back on something, even if its just walking, Monday. Sometimes you have to be tough with yourself and I don't mean beating yourself up for your weight. Yes, most of could have and should have done things differently to prevent this from happening. But by joining MFP and counting your calories you have already said that you are ready to move on. So be tough with yourself and find the time to get out and do something, anything exercise wise. I started C25K at 320lbs, it was very hard but very worth it! You have to start somewhere, even if its just walking.

If you go over a bit, don't beat yourself up. Remember that you're probably still eating at maintenance (or even lower), so it's not like you'll gain anything back. I keep myself to 1800-1900 calories per day, but if I eat 2500, I'm still under maintenance (which is 3200). See what I mean? So don't freak out about accidentally forgetting to log cake at a birthday party. It's a once in a while thing.

Plus, you can always make up for it throughout the week. If I go over by 200 calories one day, I eat 50 fewer calories the next few days. You can also walk an extra mile or two or workout an extra half-hour, something like that.

Nobody is perfect, even if they appear so on this site. Remember, you are seeing everyone's highlights - the weight loss, the workout calories, the pictures on the boards. What you don't see are those days when they might binge or feel too tired to exercise or don't lose any weight for a couple weeks even though they haven't done anything "wrong".

As long as you do your VERY BEST, that's all you can do. You're going to have bad days; the trick is to accept it as part of life. After a while, this will be completely routine for you. Trust me. I've been at it since April, and it's a million times easier now because I hardly have to think about it. I just do it. It's like any other routine.

If it's too hard right off the bat, try doing baby steps. I started by cutting out soda, then I reduced my calories by 250 per day, then 500, then 750, then 1000. I started out walking 20 minutes per day, then 30, then 45, then an hour. Eventually, I added in fitness DVDs. I would aim to complete half of it, then 3/4, then the entire DVD.

You can't jump into the pool and expect to swim the 1600m freestyle. You have to start in the shallow end and learn to stroke first.
