How am I suppose to write a novel if I have undiagnosed ADHD?

So at my writing class last week I had to submit my personal goal for the 6 week class.  All week I had been writing up a storm trying to figure out what I wanted to do.  It wasn't until the night before my class that it struck me.  I started writing and have been on a roll since.  Due to my strike of genius the night before I decided to make myself a pretty lofty goal.  I'm going to write a novel. Ha!  I know it's kinda funny, Luke laughed too.  I think I have a good story in mind and maybe some day you will be able to read it.  They say write what you know and this... I KNOW.  :)

When I submitted my goal the teacher scanned through every one's and stopped at mine.  "Margaret?" he called out.  "Wow you are pretty ambitious." he said.

I was all like... "really?" in my little mouse voice, TERRIFIED.  "I'm just not sure what's feasible I guess."  He told me 50 pages of a novel was feasible in 6 weeks but then laughed a little.  Was that supposed to be encouraging?  I'm not sure.  Hmmm

Anyways... novel gang here I come.  That's what my small group is called.  On Tuesday I submitted my work so far to my small group so they can tell me how much it sucks tonight at class.  Sounds fun!

So far I have been doing a good job with writing when I have free time and sometimes going to the coffee shop during lunch to write but once in a while I get what I like to call "Facebook ADHD" which is when you are doing something productive and a power comes over you so strong that you MUST check facebook.  From their it's a downward spiral of photo viewing, news feed checks and other blogs reading... you might as well give up what you are doing altogether.  With this undiagnosed ADHD I don't know how I'm ever going to complete my 50 pages in 6 weeks.

Wish me luck!... Oh and READ my book.  When it some day, if ever, gets published. :)
