Hi Cassandra,
Tammi always has great advice when it comes to writing, so I would definitely take advantage of her expertise.
My advice and one thing that I try to do because I tend to
over-edit myself is trying to write in two steps. Write down what you want to say and don't make any effort to do any editing. I know it can be hard, but if you separate the writing portion of your process from the editing portion, you may find you get a better flow and its easier to at least get down on paper what you're trying to say.
Hope that helps and good luck!
