Sibling Rivalry or Something Else ?

Again, an argument began,
Again another fight broke out,
Again the night silence breaks,
Again I take it as you shout.

Again I lock myself in the bathroom,
Again Your demanding to open the door,
Again, I'm trying to figure out what to do,
Again I'm sprawled out on the floor.

Again you finally break the lock,
Again I close my eyes and cover my ears,
Again you grab my arm,
Again you don't know your strength you have acquired through the years.

Again You say I'm the one with anger issues,
Again you yell "You can't just run and hide,
Again You say how stupid I am,
Again I try to commit suicide.

Again you finally calm down,
Again you leave me confused,
Again I ask the same question,
Is this normal or am I being abused?

Again I force myself to think the same thing,
He is my hero He is my older brother,
This is how he teaches me,
And we will always love one another.

*He may bring me tears and bruises but I still believe he loves me because out of my family he is the only one who hasnâ??t lied to or abandoned me*
