I've been playing Dungeons and Dragons for the last few months and I finally have a character that has truly grabbed my interest.  I think about her more than any other.  I want to flesh her out and write stories about her outside of the weekly gaming session.  I get excited about it and even came here to see if I could role play her even if it goes way beyond the campaign she's in.  

The problem I am coming across is that as soon as I am prepared to start her journey it's like a gate in my mind just slams closed and I am blocked.  I can see through, but I can't reach in and pull her out.  

I don't know how to fix this.  

I haven't role played in a forum or text based anything in years.  Life got in the way of this hobby that I loved so much.  Now I can't seem to figure out how to get back in.  

What do you do when you get stuck?
