Frankie Sandford is proud to have overcome her depression this year.The Saturdays singer - who was admitted to hospital at the end of last year in a bid to beat the mental illness after suffering from panic attacks - is delighted she has moved forward in 2012 and has been able to use her experience to help other sufferers. She said: ''After a really tough couple of months for me last year, this year has been really positive. I'm proud to be an ambassador for the mental health charity MIND - I'm able to share my experiences with others and hopefully help those in similar situations.'' Frankie - who is dating soccer player Wayne Bridge - has previously revealed depression made her feel ''worthless and ugly''. The brunette beauty - who has been plagued by the condition since the age of 15 - said: ''Suddenly my illness had control over me. ''I got upset because Wayne hadn't bought the right yogurts; I managed to convince myself he didn't know me at all. ''It set off this spiral of negative thinking - if I disappeared, it wouldn't matter to anyone. In fact, it would make everybody's life easier. I felt that I was worthless, that I was ugly, that I didn't deserve anything. I had some counselling which helped for a while but then I stopped going when I felt better.''
