Savior! I've no one else to tell

Savior! I've no one else to tell --
And so I trouble thee.
I am the one forgot thee so --
Dost thou remember me?
Nor, for myself, I came so far --
That were the little load --
I brought thee the imperial Heart
I had not strength to hold --
The Heart I carried in my own --
Till mine too heavy grew --
Yet -- strangest -- heavier since it went --
Is it too large for you?
