Drew Barrymore
has come a long ways since her wild childhood days!

The "He's Just Not That Into You" star covers the February issue of Marie Claire, where she opens up about her unstable teenage years and her current relationship (or lack thereof) with her mother.

While Drew has found stability with her new family, hubby Will Kopelman and their beautiful little girl Olive ... Barrymore's life hasn't always been so secure. 

"When I was a kid, everything was so unplanned, my parents were so erratic, and my world was so inconsistent," she tells the mag.

"I was 14 when I moved into my own apartment. I was so scared. I didn’t know anything. I didn’t know you had to throw food out when it rotted in the fridge. I was convinced someone was going to crawl through my window. I would go to the Laundromat and sit there reading Anne Sexton, Sylvia Plath."

The actress -- who stared smoking, drinking and doing drugs all by the time she was just 13-years-old -- has always had a troublesome relationship with her mother.

The 38-year-old has even said, that as a child, she questioned whether her mother was actually her parent or her manager. Even today, Drew says she still distances herself from mom Jaid Barrymore.

"Ugh, I mean, my relationship with my mom is so complicated that…I’ve always been empathetic toward my mom, and I was even more so when I had a kid and we had a really amazing conversation about it. However, it hasn’t enabled me to lessen the distance. It’s the hardest subject in my life. I’ve never just been angry with her. I’ve always felt guilt and empathy and utter sensitivity. But we can’t really be in each other’s lives at this point," she admits.

While Drew may have been a handful as a kid, she's really grown up into an amazing woman.
