Hi... me again...

As I'm in this position of having writers block and have to write essays and such in school I'm having this delema... I'm in this writers course and we have to write this text (we could chose to write whatever) with the theme "metamorphosis". This text is going to be off course graded, but also we have this writers contest in our school where this is the theme too... and my teacher wants me to send my "text" to the centest and I don't really know what to write!!! HELP! As I'm in this writers block stage I don't know how to write down or what to write down. I have this image in my head of a world in the future that's like taken over by these creatures who are very powerful and there's just a few human people left on the earth. BUT LIKE I DON'T KNOW HOW I'M GONNA WRITE IT! OR IF IT'S LIKE A GOOD STORY LINE OR WHATEVER!!!!!!???? HELP? PLZ??? 

And since I have this really bad writers block I JUST CAN'T SEEM TO KNOW HOW TO WRITE THE LAST CHAPTERS OF HMRBB AND TMLS! *SOBBING LOUDLY* AND IT WILL PROBABLY TAKE A WHILE BEFORE I CAN UPDATE AND IT MAKES ME WRITE OTHER STUFF TOO... MAKING IT VERY HARD TO WRITE ON THE THINGS I NEED TO WRITE ON LIKE MY STORIES.... AAAAGGGHHHH!!!!!!     :(
