I need to write a Philosophy essay but don't know how?

I don't know how or what to reference.
Whether I state me own opinion, do I write 'I' in my essays?
How to start it off.
My essay question is based on a short piece of text and I feel like i'm just going to end up re writing the text!
All I want is to look for some essays online just to get a feel for them but there are none, i'm guessing because of plagiarism. So scared my first essay will be crap and It goes towards my final grade!!
