My hair has been cut too short and i look like a boy PLEASE HELP?

Hello, im 19 and i have been desperately trying to grow out my hair but it has been so damaged at the ends, so i thought it would be a good idea to have it cut short, my hair was just touching my sshoulders before and i wanted it very similar to ashlee sSimpson'snew hair http://www.google.co.uk/imgres?imgurl=http://www.glamour.com/images/beauty/2010/10/1020-01_best-short-hairstyles-ashlee-simpson-pixie-cut_li.jpg&imgrefurl=http://www.glamour.com/beauty/2010/10/7-y-short-hair-ideas&h=338&w=286&sz=27&tbnid=-0ptKwNQRBzQLM:&tbnh=119&tbnw=101&prev=/search%3Fq%3Dashlee%2Bsimpson%2Bpixie%2Bcut%26tbm%3Disch%26tbo%3Du&zoom=1&q=ashlee+simpson+pixie+cut&hl=en-GB&usg=__2yRb_heViHoJ7adVi88hPQ2gi1w=&sa=X&ei=qD_uTe2dKMqAhQex6c2iCQ&ved=0CDkQ9QEwBA but instead it is much shorter with a barely there fringe, I'm so upset i look like a boy and i have just lost all my confidence, i don't know what to do to make it look better, please can someone help x
