Well, it counts that you admitted it! That was a long time ago and as long as you don't do those things anymore, you're fine! I'm really glad you confessed, it shows you're brave, mature and you take up responsibility for your mistakes. That's why I respect you.
It doesn't matter that you made mistakes, just that you learned from them and grew to be a better person.
If a 9 years old girl makes an apology thread, it actually means that they're very sorry and mature. I forgive you.
Yo have gained my every respect! It takes courage to admit your own mistakes I don't know you very well - unfortunately! - but by just reading this I know you would be an amazing friend. The past doesn't matter anymore.
