I have a dark secret.
What is your dark secret?
I'm thinking of killing my brother.
It is wrong to kill.  What has happened for you to be so angry about your brother?
I want him to feel insecure and alone just like I feel all the time.
Killing your brother is not going to make you feel any better. Please get some help because this is not normal. I am sorry if people have rejected you but you seem to be in a very dangerous place.
