Pregnant and terrified!!

Ok yall. I already have an 18 month old little girl that's my everything. I have a great life as a stay at home mom. My marriage is currently recoving from an affair, but honestly better now then ever. Hitting rock bottom has brought him closer to God. But I'm still petrified of having 2 babies. Please tell me having 2 babies 2 years apart is possible and not a disaster 🤦‍♀️

My little still doesn't sleep through the night. And I'll I can think about is how hard it's going to be! Y'all. Tell me this is going to be ok 😭
