Can't sleep cuz I need to park the car.

Tomorrow is my last day to workout with my trainer and I can't sleep. Ugh!!! I am worried about what will transpire in the next few months. In the next two weeks I will be preparing for my surgery. Things at the office will need to be settled and ready for my absence. My time for workouts will be limited. I worry about what will happen. How much weight loss can I maintain? Will I gain since I can't maintain my exercise level? How will my food habits change? How much will I regress physically? I so do not want park the car. This part of the journey is definitely challenging. This part of the journey is a fork in the road and I am unsure of the road that lies ahead.
