I didn't sleep at night through my whole last tri.

Honestly, there isn't really much of anything you can do... The breathing, my doctor prescribed me an inhaler. But it was for more for shortness of breathe from my anxiety then being pregnant.
and for the sleep, try drinking some black chai tea with a little bit of vanilla and milk before you lay down. That helps a little bit. :)

How do you mommy's cope with it?? I'm literally wide awake

Lol yes it is girl yes it is

I'm on vacation this week and the insomnia didn't really start until friday night, plus taking naps during the day doesn't help either

Yes, ma'am. Some people have it worse then others.

yes ugh and it's the worst
