Honestly, my childhood sucked, and I would hate to relive or change it. Don't get me wrong, I loved being a kid. However, every day I wake up I am one day older and I love it. I'm only 19, but I see marriage/children as my number one goal in life. Also, I have never had a girlfriend (so I have a lot of work to do, lol.) I realize that getting married before 25 can be a devastating mistake. So right now, I feel that I am in a point of my life (age 18-25) where I kinda just want it to be over. At the same time, I am having a lot of fun with my life, so I'm not complaining about being 19. When I was 16, I definitely didn't think about marriage, so your goals will change over time. Just roll with it. So if "growing up" makes you scared, just think of something awesome you want to do in the future. Hopefully, that will make you feel better. If it is something serious like marriage or a career, you can start basing your life around it.
