Re-joining the work force after 12 years 😱

I’ve been a stay at home mom since my oldest was born, that was 12 years ago. I have two more kiddos (youngest is 6). So, all I’ve really ever known is being a mommy. I worked before I had my oldest but only for a few years at a daycare.

I’m supposed to start a job working for the county starting at the end of the month. I am a nervous wreck!

Any advice on how to adjust to this transition? Anyone else ever rejoin the working world after a long break?

Thanks in advance!
