I love that you have done this for yourself!
When I start to feel overwhelmed, I have to break life down into steps. I make check lists of errands or chores (I hate cleaning with a passion). Even small accomplishments help... like taking a shower, eating enough to take my vitamins without getting sick, getting one load of laundry done, etc. Mostly, I like crossing things off my list lol. I might not even make it out of my house, but I did SOMETHING.
I have a tendancy to get stuck in my head. I have been know to sit down and read for hours and hours. It's only until I go to try turn my head that I realize my neck has gotten locked, and all the sudden it's afternoon!
You mentioned writing fiction. Do you mind if I ask, how you got started? I have been thinking that it would help having an expressive facet. Short stories? Blogging? I was hoping for a suggestion to break the ice.
