Sometimes I just want to cut myself..

Sometimes I just want to cut myself,
And honestly I don't know why.
This life at times just isn't worth living,
And it gets to the point where I want to die.

And what makes things even worse,
Is that you had to go and break my heart.
So now every time I see you with another,
My heart gets completely torn apart.

I don't know if I should be jealous,
Or even if I should get mad.
But your girlfriend has something I never got,
Or something I never had.

You keep her close to your chest,
Where your feelings are always true.
And I can't tell if you mean it,
When you tell her the saying ' I love you.

Oh dear god please help me now,
Because I don't know what to do.
My mind tells me to stop everything,
But it's so hard to stop loving you.
