You have cleared the path and you only now have to decide to walk it. You had an inexplicable feeling of restlessness which might have been confused with anxiety. What you felt was an awareness that you have done the things you knew would place you in a position to manifest the life you desire, and you also recognize nothing is standing in your way due to your efforts.
So now you also understand the power that you hold because of what you have already accomplished, and that can cause you to become anxious. You now get to decide to either let that emotion stop you, or you can choose to turn it into excitement and use it. When you recognize you have a choice, you will make the right one.
