I'm often invited to parties, but the only way I can go is if I lie to my parents and say Im staying over..?

I'm 20. Take this from somebody who's been there, done that. Like you, I used to do that. I used to lie to my parents, telling them that I was having a sleep over with friends. It was all lies. I used to go to parties and get wasted. Until one day, I was so drunk that I went into a bathroom with some guy I barely knew. We were making out and it was leading somewhere that I didn't want. I tried to leave but he wouldn't let me. He started taking my clothes off and almost raped me. If it wasn't for somebody that heard me, he would have succeeded. That made me think ; imagine if he would have done it? My parents wouldn't had an idea. That made me want to talk to my parents and let them know exactly where I was at all times. Think about it. Don't go through what I went through or something worse. It sucks because until this day I can't forget that day. I'm pretty sure that if you talk to your parents, they will understand you. Good luck :)
