How to move on from humiliation?

When I was in 8th grade I was friends with this 10th grade girl we both like this guy and his brother. I didn’t had a phone so I used her phone to check my Facebook and I didn’t log out then I remembered that I had messaged one of the guy and was talking bad things about her saying she’s flat and I was getting the guy mad talking bad about him then he called me a square goat which is bad of me I don’t remember the reason I was saying those stuff maybe cause she wasn’t as a good friend to me like have me like a dog and act like she’s a queen. Then when school over she came to me with one of her friend and told me off that she read the message and how she don’t want to be my friend anymore and that sameday I gave her a gift for her birthday and she said you can have your gift back I don’t want it then she said she’s going to visit my parents. She came the same afternoon and was reading all the message and she was trying not to laugh when she read the square goat one, then my mother was coming for me and then my dad called my grandmother and it was a whole mess. I felt so humiliated and disgraced. I know I deserved it. What she did there will stay with me forever.
