Sunnyflower, take a deep breath and try to relax. These are just THINGS. Once you move, you will see that when you unpack, you will think "Why the heck did I cart this all this way.." A good rule of thumb, if it doesn't have extreme sentimental value, then don't bother, you won't miss it. And if you really need something you got rid of, you can replace it when you get here. Moving is just a check list and once you go down the list, it becomes less and less overwhelming. Also, think of it as a chance to purge. I know that you are probably thinking that you need to hang on to everything as a connection to your old life, which makes it even worse.
Moving is just plain overwhelming but try to focus what is really important. You will get through this! and come out better on the other end. what doesn't kill you makes you stronger.. And moving thus far, hasn't killed me (and this was my 5th major move!)
