Trying not to give up!

I'd say try to forget about the last few weeks and don't get down on yourself. Just take small steps to get back on track. You don't have to change all at once, but I think if you just go to the gym once or twice you'll start feeling your motivation coming back. And great job so far! 20 lbs is a real accomplishment!

NO GUILT!!! It is a bad thing. When you slip, just get right back. You have done it for 110 days and lost 20 pounds which is wonderful. You can do this and you are worth the time and effort.

20 lbs gone is a huge accomplishment and you can get back into the swing of things. Do not let this time turn into a relaspe of old habits. You will feel better if you just get off the couch and get moving ..good luck

You've come so far! Think about how hard those first 20 pounds were to lose...if you slide back now and regain them, you'll have to start all over! It's so much easier to keep moving forward than to take huge steps backward ad have to back track and start all over again!
Since you've slipped up a little, try easing back into it. Set small goals, with small rewards in place. Maybe your first goal is just to stay within your calorie goal for 2 days. If you do that, reward yourself with something small, non-food related, such as buying yourself your favorite magazine. Then you can go from there. Next your goal could be staying within your calorie goal for 5 days. And then once you have the food back under control, add back in the exercise in the same way. Slowly build back up to where you were. Start with a goal of 2 workouts a week and then increase once you reach that goal until you are back to where you want to be!
Another good way to motivate yourself is through progress pictures. Look at images of yourself 20 pounds ago, and then currently, and see how much your body has changed! That can be an awesome motivation to get back on the horse and keep moving forward! You can also make yourself a little vision board. Fill a piece of paper with inspiring images and quotes, and a list of all the reasons you want to get healthier and lose weight, and then hang it somewhere you will see it everyday! It's like a daily little pep talk from you to you!
Ask your friends and family for support and accountability. Ask them to check in with you each day and ask how things went. Knowing you are accountable to someone can help make healthier choices a little easier!

You got to put that behind you and reset! Set new goals! State your motivation! Don't slip back into your old ways! You are strong person and you can start all over right now! Do it for your kids! Don't you want to live a long healthy life for them? Don't you want to be a good example for them? Imaging fitting into your goal outfit! Be that person that got it together, lost the weight and kept it off! It takes serious dedication and motivation. Be the person you always wanted to be!! No excuses! You have one body, one life! Don't take it for granted!
