I know this feeling pretty well. But I'm also sure you can do this. You have 1 month to go, it's 30 days starting from today. 9lbs to lose, it's 2.25lbs for a week. You CAN do this!
Stay on track, stay 100% on the diet and be VERY strict with what you eat. Best would be just stick to exante meals without any other food at all (less temptations)
If you exercise, keep in mind that you are not trying to build up muscles....that's not the goal at the moment. Do not overdo the exercise because:
1.you will feel hungry and crave normal food -easy to fall off the track here;
2.you will gain in muscles weight, while still losing fat - muscles weigh more than fat because it is a denser product. 0.9g/ml. - great example there:

Once you get to your final goal and start introducing food during the maintaining phase, then it's the great time to step up your exercising routine and push you as much as you can, to build up muscles, to shape up, speed up metabolism and feel even more amazing.
I heard many stories of people who started exercising and put on weight or stopped losing completely. But what they didn't check was the body measurements. You know what I mean, you will look slimmer because the muscles take less space, it's dense. Imagine 1 pound of apples vs 1 pound of feather...
Dolly, to keep it short... you are doing great and no need to stress about it. You will get there. It's not going to be easy but very worth it in the end.
Keep going and stay focused!
