What should I do for my birthday?

I am turning 15 in two days, and I don't know what i want to do for my party. I don't know who to invite, not that you guys would know my friends but I was wondering if I could have some advice on what kind of people to invite..like should I invite both girls AND boys, too? Should I have a sleepover and invite just my BFFs or some not as close friends too? Also I have a friend who is annoying sometimes and isn't into girly things, and I also have a CLOSE friend who sometimes causes drama should I invite those two? Thanks and hopefully you guys know some advice..
