Suddenly lacking all motivation

I think you should do your best to set realistic goals for yourself. it's absolutely amazing how far you've come, and it's understandable that you feel a bit burned out. How much do you want to lose each week? Half a pound? Are you ready to seriously work on weight maintenance?

I think you learned a valuable lesson from this. No half measures. There is no neutral in life. You are either moving forward or falling behind. For every thing in life there are a million reasons to do it, and a million reasons not to do it. You have been choosing from the "Not To" side. And that's fine. Maybe tomorrow you will choose from the other side. All I know is, and I think you are seeing this now as well, every time you choose from one side you are that much more likely to choose from the same side tomorrow. And so on and so on and so on. One day, maybe tomorrow... choose differently.

Ok you had a lot happen and it sounds to me like you are tired and just giving in. Been there done that. Here are some tips that have helped me:

1- Don't buy any junk. You are living alone, just keep what you need in the house to make sure you can eat and your daughter on weekends. Won't change the amount you eat, but at least won't be junk.
2- Don't stop home, bring your gym clothes and go straight to workout.
3- Work out in the morning. I find I do better if I workout in the morning, it sets the stage for the day
4- Home workouts - Videos, weights, or just get up and walk during commercials

2 lb a week may be a lofty goal to set for yourself now that you have less to lose. Maybe try for 1/2lb a week for a little while and then slowly increase or update.

Hmmm... I tend to be happy when it's around 2 pounds a week lost. I don't think I'm actually at a maintenance place yet, I look good in clothes, but without is still a different story and I want to feel good about how I look!

Maybe I am a little burnt out, but I am stubborn and really want to finish this journey!

2 lbs a week is a bit aggressive if you're only looking to lose about 20 lbs now. Certainly not realistic based on your profile picture. Maybe that's part of the problem. Perhaps try a smaller calorie deficit that's easier to live with and will give you a more appropriate rate of loss for the amount of fat you have stored now.

Try and take it back to basics. Write down all the reasons you want to do this. Focus on meeting your (increased?) calorie goal and look at where else you want to make changes. Don't be too radical though. Make changes you can live with. Part of your mind is obviously resisting feeling like you're on a diet, so try to avoid that. Maybe don't divide foods into "healthy" and "crap" but focus on meeting your calorie goal while getting plenty of nutrients. Don't put so much pressure on yourself. Losing weight isn't easy, don't make it harder on yourself that it has to be.

Set yourself small targets regarding exercise. Sometimes when you get out of the habit, it really is just mind of matter and you just have to make yourself do it. You're already dressed, so force yourself to make the next step - get out of the door. Get to the gym. Make yourself set foot in the gym. From there, it will be a lot easier. You might stay for 5 minutes, but it's a lot more likely that you'll stay longer and have a decent workout. And then, the next time will be a little bit easier, and you'll get back in the groove. If you come to the conclusion that you're really not enjoying your gym workouts, then maybe it's time to try something different that you will enjoy.

You've made great progress, congrats! When I'm feeling unmotivated or in a rut, I like to mix things up. Try a different class at the gym or treat yourself to a new workout DVD. Having something new to look forward to or be excited about might help!

No matter what life throws at you, I'm sure you can conquer it if you try your very best. "Whenever you feel like you want to quit, think of why you started" Don't give up, make time to exercise and have a plan! Talk to other people in your life about this and how about you can go doing this. "If you fail to plan, you plan to fail" You have to change your mindset in a positive matter. Hope this helped in some way.

Agree with many of the comments above, especially about getting the "crap" food out of the house - remove the temptation. I see you've joined another gym and committed to work outs 3 days a week. Good for you! You obviously know what it takes to get your weight down. Hopefully the gym can help you with maintenance work outs once you achieve your goal. 2 lbs a week sounds like a lot, but not sure what you are willing to do to achieve that. Pace yourself. Finally, Congratulations on how far you have come on your journey - you are amazing!! Now get rid of the junk food in your house!!! (that's the kick in the butt you wanted)
