It's all a matter of perspective and what you think you want. You can turn anything into as much fun as the situation allows. It depends on YOU. You can do this.
IF YOU'RE A CONTROL FREAK, TAKE CONTROL. FIRST, TAKE CONTROL OF YOURSELF. Deep breath. You put yourself in this position so you could grow beyond your comfy boundaries. There are things and people out there that are just as comfy, as inviting. People are going to like you, and learn to love you and your family. (No, nothing is EVER as good as family, but going home for visits is even sweeter.) You've had the gift of living close by, now it's time to gently push those boundaries and grow again.
2) ORGANIZE. Organize your family and your possessions so they are easier to pack and move. There's room for all the memories and some of the stuff. KEEP IT SIMPLE.
3) LEARN. As soon as you know where you're going, begin to research it. Each day, learn something new. Then it won't be so new or foreign - when you see the place for real, it will be familiar. Make it exciting and fun for you and your kids. Create map games - can you find the 'x'.
Look at a map - try Google Maps - look at the streets, learn street names, look at the street view and the satellite view to see the terrain. See what links the local Chamber of Commerce and City, County and State governments have on their websites. Learn the history of the area. Who are/ were the indigenous peoples? What are the architecture styles? What museums are there? What's the weather like? Playgrounds, schools? Medical centers? Universities? Libraries? Public gardens? Parks? Hiking trails? Camping? Foods? Sports? Language? Depends on your interests and needs. So much to see and learn, so little time.
4) Have you noticed any general time schedule or regularity to your moves? In any case, expect to move and always be ready. That decreases the anxiety, and makes the process easier because you're ready. You can live comfy and settled in to a place while being ready to move.
5) Made sure your kids think moving is the neatest thing to do, like going on some kind of long-term vacation. Try not to let on that it can also be difficult. Tears and warm goodbyes are a given. Embrace them.
6) Packing up is part of the fun. Let your kids choose some of what to donate or toss, what to store, and what to take (within reason - they set specific limits). Unpacking and moving in to a new place is like Christmas; the BEST part is that you can play with the empty BOXES! Make forts, tunnels, draw on them, and when they wear out - flatten them/tear them up and make sleds that work on GRASS. You can even go out to play.
7) Get one of those blank journals or a notebook, and collect quotes you like. Then, they are there for you to read whenever you need a lift. Inspiration can be found everywhere. Scripture, novels, famous writers and poets, John Muir, Emerson, Walt Whitman, Maya Angelou - the list goes on and on. Even Oprah sends out inspiring quotes!
Hope this helps! Good luck and happiness in your new home.
