Keep me motivated!!

You're not supposed to stay motivated, and you have to find the "why bother" inside yourself. I can understand why you struggle, if you have happy living on the one side and healthy eating on the other side - it's surprising that you can stick to more than a week.

What you can do (and I think you must), is to make healthy eating happy. Not by telling yourself repeatedly how much you love broccoli, but by actively choosing foods and meals you like but don't overeat, and experiment to discover meals and meal schedules and portion sizes that keep you going. No foods are off-limits, and no foods are so healthy that they can be eaten in excess.

When you hit goal weight, that's when the challenge starts for real, but if you've found a diet and exercise routine you like, it's not going to be a struggle. You know it's a good plan when you can decide you'll just as well stick to it. If you want to go back to your old habits, you will, and then you will go back to your old weight too. Maintenance is for life. If you make a plan you want to keep (just with small adjustments) for maintenance, not only will the transition be smoother, you'll actually be able to stick to it until you reach goal weight.
