Anxious About Transitioning from SAHW to FT Employee

I graduated college last August, and in October, my husband and I got married and moved to Texas. Since then, he's been working full time and I've just been a stay-at-home-wife. But a couple weeks ago, I went on my first post-college interview, and I ended up getting the job! It's a full time job, and I'll be starting next Monday. While I am very excited about it, since it is my first "grown up" job, I'm also TERRIFIED! It's going to be a huge change from being a housewife, and I'm anxious about how well I'll manage the transition. If anyone has any tips for handling the adjustment from housewife to full-time employee, or just for handling new job nerves, I'd love to hear em! Thanks!
