i can kind of relate to this as well.

when i had to write my first essay, it was okay.. because they gave me a topic to write about- and just said. go on, argue your case- for and against such and such

but then i had to do 1 on my own... of a topic of my choosing- and i chose alton towers theme park (perhaps not the best choice, but anyway)

i spent weeks and weeks collecting stuff about the park.... figures, stuff about the rides, stuff about the history.. but my problem is i know what i want to say, but not how to say it.

so i knew i wanted to say like... this is alton towers theme park, it opened in such and such a year, and on it's first day it atracted so many visitors and have the following atractions.. but well my anxiety got in the way of it all and i ended up just copying and pasting all the artickles i found for it.
