Diane Keaton never expected people to understand her eating disorder.

The Oscar-winning actress has suffered from bulimia in the past but says she kept it a secret because she didn't want sympathy.

She told AARP The Magazine: ''With bulimia, I never expected sympathy or for people to understand. What I cared about was the secret I kept. It felt like a burden. I never told my mother. It's amazing how the dark secrets inside us don't matter much to the outside world.''

The 66-year-old star also revealed she would consider cosmetic surgery in the future but has so far resisted it.

The 'Annie Hall' actress said: ''I haven't had it, but never say never. Because when you do, you are definitely going to go there. I said I would never have intercourse before I was married, and I did. I said I would never go to a psychiatrist, and I spent much of my life in psychoanalysis. I've done all kinds of things I said I wouldn't do and, of course, now I'm glad. Thrilled.''

However, she says she's not worried about ageing and feels grateful to still be here.

She explained: ''Let me tell you the best part about getting older. The best part is that I'm still here and, because the end is in sight, I treasure it all more. That's why I don't worry about crying in a scene anymore. Now it comes easily. I know the emotion's all there.

''You have to live life that way, you know? Take risks. Do things you can't imagine. 'Cause hey, why not, right?''
