This lays heavy on my heart, I'm sorry for being so mean to you. I'm sorry for the things I've said, and all the hurtful things I said the past week out of anger. It was very unfair and mean-spirited of me. I realized my mistake and what a horrible person I've become.
You have been such a great friend all these years, I cannot stand losing and damaging our friendship because of what I did. I will try my best to set things right between us, I hope in time you would find it in your heart to forgive me.
