Hi Shade, I sympethise, my youngest daughter - she's fifteen now, was similarly easily bruised at school. Even at home, if she said something funny, as little ones do, and the family laughed, she would cry for ages. Your daughter will grow out of this in time, as her social skills develop. You need to reassure her, and affirm her at every opportunity, telling her she is loved, and valuable, and a good person. She will start to believe in herself as she grows. Always accentuate the positive to her about herself, and avoid the temptation to say that her friends are nasty - children find their own way through the world - with love and care from us.
