could use some help with editing

I'm a very slow person, that fine sometime I type faster then I am thinking and will really mess up a line or story in a heartbeat. I also have problems with memories, mainly due to age (over 60 young) and brain injuries. However I enjoy all I read here and often wish to post an idea or story that I was thinking about. I also have total forgotten how to write as I was taught back in my jr years of school and collage so any help would be great.

Thanks
