Honestly, once I left for college, even though I was still 17. Once I was out of the house and responsible for my own life, basically. My parents didn't coddle me...no helicopter parenting, didn't call me every day, didn't ever even ask about my classes or grades. I was essentially 100% autonomous. It was up to me to navigate college on my own. My parents provided some financial support (mostly helped me with rent once I had an apartment), but I got loans. I got through 4 years of school, lived in an apartment with roommates for 3 of those years, paid bills, had a job, had a car/insurance payment, paid my own cell phone bill, and was ready to get married right after graduation (met my husband sophomore year). We did get married a few months after graduation. He is a military officer and we basically jumped right into life together after graduation and his commissioning.
I stopped feeling like a kid around 15, when I got my first real job. But I didn't feel like an adult until I was at college.
