i think first off your just nervous about it being your first pregnancy so some of the anxiety is caused by nerves.
i just experienced my first preg over a year ago and i had the exact same sleeping problems for the first few weeks, until i found out i was pregnant i thought i was going crazy cause i just couldnt sleep, and fought with my fiance over this, bc he loves his sleep lol. but dont worry there will be plenty of times through the preg when u'll feel like your losing it, but its just your raging hormones, ask your doctor to explain to you what happens to the levels of hormones in your body whilst preg, your baby is making there little nest inside you so your sharing your best resources with them for nine months its no piece of cake. just remember its natural to feel vulnerable, and it gets easier as the pregnancy progresses, until at the end when your too uncomfortable to sleep again, but you'll be fine, just relax its normal to experience doubts, theres never an easier time to have a baby. its not how they make it out to be in movies!
Your body is just adjusting, but pretty soon all you'll want is sleep.anxiety so natural at this stage, it comes back after the baby is here too because again your hormones are adjusting to a new body without the baby. just take control of how you react to the changes, meditate, and remember your gonna have a little pressie that will make everything you experience make perfect sense, and dont worry you will return to your prior self- the one who had the ability to focus and feel level headed, you may only get to experience this once so enjoy
and if not yet involved try joining some groups they help at times when you need to talk to someone besides your hubby. My fiance was brave for sticking with me when i was pregnant, but try your best to be nice he's the one who'l look after you the most.
congrats and relax
