Constipated

I have been constipated for a week now, I'm only able to go (tmi) but balls and every time I have to poop my stomach hurts soooo bad because not all of it will come out! I've drank prune juice, and have taken stool softeners which usually works. I don't know what else to do but I'm so constipated to the point where it's starting to make me feel nauseous and sick. Any remedies that help? Drinks I should drink daily? (Not pregnant) help please.
