Campbell doubted her survival in fashion world

London Supermodel Naomi Campbell used to doubt her survival in the modelling world and insists she pushed herself beyond limits. "To be honest, there were times I thought I wouldn't survive. The time between 1998 and 2005 was especially bad. During that time I avoided looking in the mirror, because I didn't like the person who was looking back at me," femalefirst.co.uk quoted her as saying. The 40-year-old British model revealed that she assessed what she wants out of her life and thought of sitting and not working made her crazy. "So I had to find out what I wanted and what I didn't want. The thing is, as a model you're used to being on the go, so just the thought of sitting down and thinking about something drives you crazy," she said.
