You feel rubbish as you're in transition - think of it as you feeling the right thing at the right moment, yay, your brain is doing the right thing :)
You're in a kind of weird free fall limbo land... You've set off from where you were, departed mentally and emotionally if not physically. Here are the mixed inagery, but jumbled up is probably quite fitting for this moment :)
You've raised the anchor, pulled up the gang plank, waved goodbye to the people on the shore. You're on a boat, pulling out of harbour, got no feet on dry land and no way back. You'll land but not on those shores again, maybe you can visit, but you'll never call that place home again. So, you set off, cast off, whatever! But what you do know is that you've gone, irrevocably and without a way to return.
But unlike other journeys, you don't have charts, mapless and no idea what the future has in store. So no vision to move towards, no dreams to start dreaming, no way to plan for what's happening next... Just blankness... And waiting.
So, yes, how do you feel on this water craft? Full of possibilities but no actualities, full of hazy future and the background receding into the distance behind you. Loads of questions, no answers... Just the bright blue sky and the horizon a line hovering between blue of ocean and blue of air.
So, you might feel rudderless, Maybe you feel like you haven't even got an oar (or a captains wheel depending on the type of water vessel you're visualizing!) ... But let's just step back here. Cos this bit, it's just your brain hating the uncertainty, you actually have loads of navigation tools and ways to shape where you land. You have to remind yourself and get some confidence back. You have skills, a profession, experience, cv, recruitment agencies, companies etc etc etc.
It's uncomfortable having to rely on your skills to cross the sea when you were happy as a settler on land, but now, you're a nomad, an explorer and a pioneers, you're free and free is scary. But you'll be ok, you know you'll get another job but right now, you just don't know exactly where you'll land yet.
Embrace the vertigo, the freedom and the possibilities. Be a nomad just for a while, before you put down roots and settle into a new work environment.
