Essays / Psychology Opinion Paper (pointers/suggestions needed) [3]

I am supposed to be writing a term paper for psychology. It is supposed to be 5-7 Pages long. I can choose any topic but it needs to be an opinion paper and I am an awful writer and I'm not sure where to begin or even how to start an opinion paper. I'm also not completely sure what a good topic for this paper would be. If someone could give me some pointers/suggestions it would be greatly appreciated

Thanks
