I miss being a kid? Anybody feel the same way?

I'm 19. I miss being a kid so badly. All adults ever think about is , , &.......................... more . I hate getting into adult conversations. I'm still living with my parents & my baby sister. My sister is scared of sleeping by herself, & she doesn't understand why she can't sleep with my dad & stepmom. Well we all know the reason why, but you can't tell a 5 year old that. I hate college too. Everybody tries too hard to be cool in college. College is a freaking joke. At least I'm getting an education & a degree one day. That's all I get out of going to cl. I don't even go to the MMA gym anymore because all the guys there are perverts around women. I just work out at my private gym now. Being an adult is f*cking senseless. Any advice on how to make life better? I'm 19 & still feel like a kid even though legally I'm an adult.
