Your suggested topic of the problem of domestic violence has been effectively portrayed in film, so it can clearly be equally effective with photojournalism. To this day, the memory of a woman who testified why she finally murdered her husband is haunting in the recollection of what this pitiable woman's face looked like as she sat in the witness chair.
You might want to pick a theme such as "globalisation" or "poverty" and then use your photo essay to explore how these abstract concepts are reflected in your locality through images. If I was looking at globalisation for example, I would take a picture of our local mosque, an Asian supermarket, women in full veils walking around, etc - all images that reflect how globalisation is impacting my locality. Just an idea... hope it helps and good luck!
If it is a photo essay where you have to photographically document what you see in the picture and describe it in words your best bet would be to take a picture of something in cycles, for example, a bud opening slowly into a blossom, or a baby bird hatching out of an egg, a flower dipped in color water slowly absorbing the colors into the petals....
Those things are sequential, give lots of room for description and shows the effort of the photographer in waiting, with the object, for it to go through a phase. Try it and let us know how it went!
