First of all: calm down.
There is no standard way to start your journal - the other person who did EE2 in my year started hers with nothing but the date and then printed out web pages that related to her central concept.
I started mine differently. My teacher gave me a sheet for character creation that had things like "Physical Attributes: Name, Age, Height, Weight, Skin Colour ... Personality Attributes: General, etc." so my very first entry was the date plus that sheet, and then my answers to those character prompts.
Remember that how your structure your journal and how you fill it is up to YOU - start it in your own way, with whatever is relevant to your idea/story/etc.
