I have an informative essay due and im completely lost
Informing whom? About what?
One good place to get help is this website:
guidetogrammar(dot)org / grammar/index(dot)htm (remove spaces and fix dots as needed)
Click on Essay and Research Paper Level. A long menu appears. Scroll down to Patterns of Organization and choose the kind of informational essay you want to write (explaining a process, comparing/contrasting, etc.). Also pay attention to Structural Considerations (thesis statement, introduction/beginnings, etc.) and other sections that can help you with any difficulties you may have.
