Help....crazy party!!!!?

Ok, I'm currently cowering in the bathtub of my bathroom...with my laptop. (I know it's pathetic, but there wasn't much else I could do.) I happened to have posted on my Facebook page that my mom would be going out of town for a few days and I would be home alone, (she just left about an hour ago) and people just showed up at my house with booze and drugs and they're basically having this crazy *** party, and trashing my house and I'm really worried. Not just because of that but because my 'boyfriend' and his buddies are banging on the bathroom door claiming they want to have a three-some. And the door is locked right now but they're all on the freaking football team so they could easily get the door open if they slammed into it hard enough. (Even my mom did because once my sister ped out in the bathtub and my mom had to get in...but that's another story.) And well, I'm just scared and I can't stop crying and I need help. What should I do?(Cont...)
