No, no shaking - a cuppa and a bit of sympathy though. I was in a similar position before we moved and it is hard, hard, hard.
My advice, for what it's worth, is start to pack slowly, just stuff you don't use everyday - for example, we only really wear a handful of clothes regularly, so the excess can be packed. Spend a bit of time day dreaming about how you'd like the new place to look - I know you probably dont know what the layout etc will be but it's still quite nice to think about an 'ideal' home. Have a flick through some plant websites/catalogues and plan some planting perhaps. Maybe even, if you can, start to replace a few things ( I bought new tea towels, mine were old and grey and though still useful were a cheap enough thing to change over time).
Mainly try to get your mind to look forward to living in a new, better adapted home, rather than how dreadful the lead up will be. Neither has happened yet, so why not indulge the positive scenario? Otherwise you have to go through it once, but worry about it a million times.
Good luck, I hope it all happens soon for you. x
