This is so sad.... but do not let them bring you down! that is YOUR facebook account, and it's YOUR body, and it's YOUR bikini and it's YOUR life, so you can do whatever you want!!! what's wrong with wearing a bikini?? those people are really stupid... girl, there's nothing wrong in posting photos of you wearing a bikini, and as i have said previously, it is your life, so if you like even to post a photo of you completely naked you are free to do it, f*ck all them off!!! Sis, be strong, try not to pay attention to them because that's all wha they want. You have all our support. XOXOXO I hope this gets better for you :*
