Shut myself out

You told me to tell you
So tonight I didn't walk away
I stood up for myself
I tried
All you could do was sit there and scream
I couldn't take it anymore
I did what I was afraid of doing in the first place
I exploded
You just laughed
I can't take it anymore
I'm shutting myself out
I'm not taking anymore of your crap
If I can't die
Then everyone's going to lose me
I am saying goodbye to the life I used to know
And hello to my new hell
