that I have great sorrow and unceasing pain in my heart.
that I have great heaviness and continual sorrow in my heart.
That I have bitter grief and incessant anguish in my heart.
I have great sadness and constant pain in my heart.
because the sadness within me is great, and there is a continuous sorrow in my heart.
That I have great sadness, and continual sorrow in my heart.
