Oh wow! First and foremost -- congratulations! I can't imagine what life must be like for you right now, but it seems like your roller coaster of mixed emotions is totally natural. Especially with all the great things you've got going on in your life. My advice is to focus on the known variables. Find out your due date. Make sure you're healthy. Move your wedding if you need to. Figure out how to fit your new baby into your home. And also focus on the positives: Savannah's going to have a sibling! You're getting married to, presumably, the love of your life! You've got a career that's advancing! Some people would love to be in your shoes.
Finally, don't stress about the unknowns - you don't know for sure if you'll be sick, or depressed or have no insurance or that your parents may be disappointed. You can only cross those bridges when they arise. And, regarding your parents, it's always nice to have their approval...but you're an adult and you are more than capable of making, and living up to, your own decisions. They might not approve at first, but you have plenty of time to prove to them how great this new baby will be to your family and your relationship!
My parents weren't thrilled when my husband & I got engaged at 21...he was a tattooed punker kid back then and I guess they were hoping I'd hook up with some nice accountant or something. Well, I was so upset that I didn't have their approval - it sucked because it was supposed to be a happy occasion and they weren't happy about it! - but I convinced them that the future was going to be great for us and, as it turned out, it is. He's a successful entreprenuer now and we have an awesome life together. That's partly because we try not to stress about things we can't control and always focus on making the best out of the positives! You can do the same. Good luck and stay healthy!
