I want to be a kid again

I am 13 and I wish that I could go back to when I was a kid.I mean, people just stopped caring about me.I have a pretty big family,I have many little kids in my family,and sometimes I am just so fucking jealous of them.I mean why do they need to get all the attention,why do others only care about them? That's just so fucking unfair.My family will always blame me if something happens cause the younger kids couldn't do something bad,I am the bad one cause I am the oldest.No one gives a fuck about me anymore.People would care about me if I was younger
