I'm in the same boat, Juicy.
I have had diagnosed anxiety for yeeears, but had it pretty well under control until I got pregnant!
Now I'm worried about everything. I mean EVERYTHING. There's not a day goes by I don't panic about something, and it's exhausting - both for me and my husband.
What hasn't helped - at least for me is how unavailable midwives are for questions. The phone number I had to contact my midwife team's message service (seems you can't just ring a person directly) just goes to the hospital switchboard. Less than helpful! I was told to go to A&E if I had questions, ffs. So, you're left with the internet for your concerns, which as I'm sure you've noticed, is a TERRIBLE idea! Seriously, stop googling your fears now if you are still doing that. It will just make you crazy. Instead, find a good book you trust.
We anxious types have to accept we can't control everything. We can just do our best with the information we have available to us at the time.
Go to your GP and get referred to CBT - I was told there was an expedited pathway for referrals for pregnant women, though they haven't heard of that in my area.
If you have concerns that can't wait, google Tommy's charity - they have a midwife line if you can't get hold of yours like me.
Finally, please prioritise self care. Do things that make you laugh (and don't, like me, then google whether laughing a lot can hurt the baby!) and relax you.
Women go through pregnancy just fine in far more perilous situations than us every day.
Good luck! I need it too - seriously, I so get it.
