Toxic

I've thought of killing people
I can be awful
I thought of committing arson
I wanted to burn down one of the schools I went to
When I'm mad, I'm abusive and toxic
I'm not proud of my behaviour
I'm not gonna defend it
It was wrong of me
I'm gonna own up to the mistakes I've made
And I'll try not to do it again
I can't promise I won't do it again
'Cause I'm not perfect
