Do I have a disorder?!
Question: Do I have a disorder?
Answers:
A disorder is something similar to a sickness. Why would you want to call your personality a disorder. Its seem that this is just the way you are. You don't seem like you are a easy forgiving person and have a tendency to hold things against others who have made you angry or hurt you.
No disorder just your personality. But think of it this way, tomorrow is not promised to anyone. Never let the sun go down or a day go by without telling your love ones that you are sorry or that you forgive and love them when you have a disagreement because if something happens, and I hope nothing does, then you will be sorry and wishing that you had of told them it was okay and how much you love them. So stop holding grudes over petty stuff and love your family and friends while they are here on earth and can speak to you.
That's no disorder - just a control mechanism to prove your displeasure. Hopefully you will learn to channel you anger into less obvious behaviour.
You have a bad case of bratty teen disorder. Only you can cure it... Stop being a little bit*h. ;)
You sound like a normal kid/teenager to me!
