Maybe It's Not a Good Idea After All?

I've felt less prone to crying since being on Prozac as of last summer, but yesterday I actually felt tears coming after hearing something I found discouraging.  I'd posted this question to Yahoo Answers the other day:

How to write fiction based on my experience with depression and Prozac?

And got this response (the only one so far):

Start small, no need to devote over a year to a novel when you can focus on short stories.

I then said you can't publish it like that.  Or can you?   If you publish it online, will anyone see it? I'm thinking not, no one reads that stuff.  No one I know, at least,  will see it that way, I'm afraid.   On this blog, the author mentions Wattpad, which I never heard of until seeing it on her blog.  I don't feel compelled to sign up because I can bet very few people know about this.   Even the blog author admitted she didn't know about it until recently;

A few months ago I learned of this magical place where people can share their stories, books, and writing. It's been called the "Youtube for writing." This place is called Wattpad. 

Another thing I felt that is that the subject of depression has been written about so many times that there is no need for another.  After all as I said in this post, I felt compelled to write about this after reading Prozac Nation. But I felt that story has already been told, so maybe it's not a good idea after all? Although some people might try to tell me that everyone's story is different.  

Believe me though, I am trying to get over this discouragement.
