I missed behave when I was younger a cruel spoilt selfish brat noone liked , and I feel guilty for the way I?

I was like that too! every little girl and boy was. Don't be so hard on yourself, I'm 16 and people still like me after all the crap I put them through. you were young, don't even worry about it. No one thinks of ANYONEEE as the young child they once were. I don't even look at people that way, I think of them as they are now, and that is how I respect them.
