Okinawa Japan

Michael has received official orders to Okinawa; 3 years with his family. Of course the kids and I have to pass a medical screening before we can be allowed to go. I didn't want to share the news until we knew if the kids and I would 'pass'. There are reasons that we may not. If we can not join him then Michael would still have to go but only for one year. We have so many mixed emotions about this. Even he says it would be easier if we stayed behind, but a whole lot more fun if we were with him. He doesn't have to be there until July. I promised myself that I wouldn't get all worked up about this until the kids and I completed the medical screening. It isn't working.
This is what I've heard about getting there. We can only take 4000 pounds of house hold goods. We have to sell both cars and get rid of both dogs. The Military will store our cars for us, but we're having a hard time (mentally) making payments on a car we can't drive for 3 years. Then again to come home to a paid for van, if it survives storage may be a good thing. We have been told that the best thing to do is sell everything and start over in Okinawa. We can leave with what ever we buy, no weight limit. Gabrielle will be 18 when we leave so she MUST be in college or she can't stay with us. Now, as far as I know she has every intention of going to college, but to be told that she has no choice in order to live with me, her mother, just irritates me.
We are all ready for a change of scenery, but leaving every thing we know behind and starting over is SOO hard. Fear of the unknown. Then I listen to Michael. He is so excited. The beaches there are supposedly really nice and he can scuba dive. His dad was in the Air Force and was stationed on Guam when Michael was a ~13. Guam is where Michael learned to dive for the first time. He has always talked about going back there. He wants to dive with all of us. Kevin loved diving when we were in the Caribbeans. I enjoyed it, Gab couldn't do it. But Michael talks about diving and eating soy soaked chicken wings on the beach. I am so glad that he is soo excited about it and talks about it the way he does. It helps me a lot. I want so bad to go and be with my husband and be with my kids in a new place. Yet, I am so scared. Not just because of the material things; I'm mature enough to see that those are just material things. There are other things.
Thanks for letting me spill my guts and my fears. If any of you have any knowledge that will help me prepare and make this transition I would appreciate it! I know there are many families that have gone and have absolutely loved it. I know if we don't go we will be missing out on something wonderful. I'll just have to wait and see if we *pass* the screening. Then if we can't go I won't feel guilty and if we do *pass* then I'll embrace it as the Lord's will for my family.
