Drew Barrymore: childhood in the public eye is "tremendous pain"
The 35-year-old actress - who first took cocaine at the age of 12 - admits the attention of being in tabloid newspapers while she was a teenager was difficult to deal with.
She said: "My hedonistic moment wasn`t that tumultuous. It just happened at such a young age so it seemed way crazier than it was. Everyone goes to a point where they do stuff excessively.
"And the majority of people bounce back. Some of them fall into the rabbit hole - I just got mine out of the way early.
"There were moments when I experienced tremendous pain with everything being so known. You`re like, `Can I f***ing f**k up or have an embarrassing moment or do anything in f***ing private?` "
However, she admits she eventually realised all teenagers experience similar problems, just on a smaller scale.
She told the Daily Telegraph: "If you`re a 16-year-old and in high school and it doesn`t work out with the guy, and everyone`s talking about it in the hallways, it`s the same feeling. It`s all relative."
