I use pro's and con's lists to weigh up whether I'm making a good decision. Anxiety and being unsure or scared are completely normal emotions to be having in regard to moving. Moving is a very stressful upheaval, no matter what the circumstances. I think change is a good thing. Embrace it. Just avoid or block out the bad things you associate with the city, and expose yourself to all of it's great aspects. You will be fine. You have made the right decision, I can tell by the way you write about it. Turn your negative emotions into something more like nervous energy and work with it, use it to your advantage. Good luck and keep us posted with your progress and any developments.
