Hello Arris.
Yes, I read the post above in the other thread. I understand that your mom called you a baby and said you should be back in diapers in front of other people. I understand that that was embarrassing to you and that you feel hurt by it.
I'm afraid that a lot of moms - put in that situation - might have said the same thing. Your behavior was not that of a 15 year old. Your lack of remorse and apology to the people you "hurt" is also something I would encourage you to consider.
I do not think this conversation will go anywhere beyond where it is now. It is clear that you are upset and believe your mother was in the wrong without accepting any responsibility for your actions.
Again, I encourage you to seek counseling if this situation is typical of the relationship you have with your mother. You can also get information online about child abuse
Childhelp or call the National Child Abuse Hotline 1-800-4 A CHILD.
I am confident you will discover that this one incident is not something that child abuse authorities would get involved in.
