Hey!
OK, some thoughts about goals. Especially where weight loss is concerned, it's important not to think of goals in terms of failure. The reason is that it's easy to say "I will weigh 140 pounds by this date," but there are many, many factors that can't be controlled. The danger is that on "X" date one might weight 143 pounds and ... of all things ... feel like a failure! Which is really unnecessary.
So, I think of a goal as something that points me in a direction--something I'm aiming for. Not as something cast in stone.
And, it's often easier to break this big overall goal--whether it's a weight and date, or "I will lose 20 pounds," or whatever, into smaller goals. For example: Figuring out what weight loss program you want to try.
Some programs fit an individual better than another. You could try--Weight Watchers. TOPS. South Beach. Calorie counting. There are tons of programs to consider! Most of these programs include setting targets--like points, or calorie level, or types of foods eaten.
By then you'd be ready to break it down into daily actions you'll take. This might be--shopping for the foods you'll need. Listing a goal for exercise. Maybe listing meal plans and snack plans.
And after that, it's Just Do It.
Does that give you some ideas? Do you have more specific questions?
I would suggest you talk to your doctor about your sleep problems. It could be that your medication needs adjusting. In any case, lack of sleep doesn't help anyone.
Good luck!
