Scared Beyond Straight

ok, so... apparently, I'm going to SeaWorld with my little cousins and baby brother to get Halloween candy, dress up, and ride rides... but the Selena Gomez costume I wanna wear and have to wear is nearly skin-tight and shows skin. As I have pointed out previously in my posts, I'm a target for perverts and pedophiles. I don't have a choice to change my costume, plus I'm in love with it, but it makes me scared that I will get sexually assaulted. I have to wear it 'cause my mum and gramma bought all of the makeup and clothes for it. Oddly enough, the makeup makes me look a few years older- just making things worse for myself. I'm afraid to go outside, but even more so 'cause of my costume now... I don't feel safe at home either, my dad's a pervert and a kinda/sorta pedophile... he goes onto sex-chat sites and talks to 18-20 year-olds... he watches porn and goes on to xxx rated sites on my big brother and my computer... he also eyes my body in weird ways when he thinks nobody is looking... he also talks a lot about sex and sexual things around me (sometimes in great detail) he even cracks sex jokes about me and my boyfriends... I'm not safe outside; I'm not safe at home... Where the hell am I supposed to go and what am I supposed to do????
