What are the restrictions while considering this? I mean.. it's worse the longer you suffer, and the more you suffer. So.. where's the limit? Without a limit I'd say something like this
At the age of 7 you are sold into a household where you spend all your days living in a cage, sleeping in your own urine and excrement, bathing only a few times a year, you are used as a sex slave with several strangers per day and pick up HIV. To help make you a good slave your ownser tied you down with your feet a few feet above a fire for a few hours until they were dark bloody stubs and. Your owner then cut out all your teeth at the gum with a razor blade. By the age of 11 the aids kicked in and you are slowly dieing of that and from a serious lack of nutrition and food. But the rape never stops, in fact even as you are dying you have a shit-stained one in your mouth and one in your butt while they put out countless cigarettes on your skin.
I could go on in this direction, but is there a worse direction? I don't think so.
