First of all you are not ugly. Everyone has their 'ugly' or 'fat' days but you are definitely not ugly. Each person is unique and has their own personal style, looks and taste which is something to be proud of. Just think of three things you like the look of yourself or your family/friends think is your best asset and whenever you feel like this again, just think of those nice things people have said or what you had thought then you will instantly think of the positive rather than the negative.
