Gone back to school (college) after being away from school for 8+ years??

I work full time, own a house with my husband, and we're TTC#1. I'm considering going back to school (part time for now, to see how I manage juggling everything) and I'm excited but scared. I haven't been to school since 2004... So long ago. My husband, boss, and mentor all think it's a great idea and believe in me. (I'll be doing online courses, by the way.)

Just wondering if any of you ladies felt the same way when you went back to school and if you adjusted easily or if you had a rough time?
