A kid trapped with adult responsibilities

Do you ever feel like you're a kid trapped with adult responsibilities? When was the switch from childhood to adulthood? Can you quantify how much of an adult you are? Are there phases? Do you have a choice to whether you're a child or an adult? When someone says "you're very mature for your age" does that mean there is actually a choice for you to be immature at your age?

For me, I feel like there's no inbetween. Some people say that I'm a "young adult" but what does that really mean? Does that mean I'm young in age like a child but still have adult responsibilities?

No need to respond to these ramblings unless you're absolutley compelled. Nor am I annoyed or frustrated at anything. Just felt like rambling today.
