For me, I felt like an adult at 14 years old. Yeah, I wasn't obviously. But I had been through so much in my short life at that point and was already ready to get married and have kids. I was done with the teen drama, the partying, it seems I had almost nothing in common with most teens in general, never mind teens my age. Adulthood hit me in the face after my grandparents passed away in 2006. They raised me from 3 weeks old and were my parents, regardless of the blood line. My grandpa walked me down the aisle and gave me away in August 2005. I had my 21st birthday on May 29th, 2006, my grandma passed on June 10th (at 62 years old) and my grandpa on November 24th. (a week after his 65th birthday) Between that, and losing the babies I have lost, nothing makes you feel more grown up...or more like you just want to go home and visit your parents, sit in the safety net for just a little longer. I'm 28 years old, but mentally, emotionally and physically, I'm much older unfortunately.
