Rumer Willis was left feeling ''awful'' by online bullies but has learned not to base her worth on what other people think of her.

The 26-year-old actress - the eldest daughter of Bruce Willis and Demi Moore - juggled working part-time at a Marc Jacobs boutique with acting and voice lessons and auditioning for roles after leaving college, but still felt judged for her looks and celebrity parents.

She admitted: ''It was really hard. I would read that stuff and feel awful. I thought, 'I don't even get a chance?' ''People still don't necessarily know that I work - they just have opinions.''

The 'House Bunny' star admits she was sometimes ''ill-prepared'' for life in the spotlight but still took the online abuse ''really personally''.

She told People magazine: ''I would go to an event and I didn't realise I needed to do my make-up,. ''Online, people really started getting ugly .... People always say, 'You signed up for this, you're an actor,' but I used to take it really personally.''

But these days, Rumer - who is competing on the current season of 'Dancing With the Stars' - has learned not to worry too much about what other people think of her. She added: ''If you let your value be determined by what other people think, you're screwed.''
