Kizzie,
I'm so sorry, I know it can be horrible, like your nerves are being chafed.
In my experience, waiting is the worst part. When you know what you’re up against you know where to direct your energy, you come up with plans, you regroup. Make lists... think, use logic... all the grounding things that give order and control back. Whether it’s bad news or good news, you have a job to do once you get it but waiting can be exhausting business because your mind is trying to do all that too soon, before you know all the facts. It goes around in circles till it collapses.
Can you distract yourself with silly things, I mean seriously stupid ones that would keep your mind partially busy? Like binge watching ridiculous things and eating junk food you love but wouldn't ordinarily touch, whatever works. I bet there'll still be the worry and stress in the background, it would be worrying if you didn't feel horrible right now. Nothing could be more realistic than feeling awful while you have to wait.
I'm thinking of you
