The thing that will help you more than anything else, Susan, is to write down your desired routine.
During one of your “better” moments, create a schedule.
It doesn’t have to be rigid, but it does need to list the things that you’ll do on each day with some times assigned to them.
Creative people, and especially those who are home all the time, need routines.
Otherwise, we drift.
This has happened to me more often than I’d like to admit.
You’ll have to revise your schedule periodically, and that’s okay; but whatever you come up with, try to stick to it.
And don’t let yourself off of the hook.
If you’re like me, then there will be days when you “don’t feel like it.”
The thing is that it’s so easy to get to where you don’t feel like on any day.
A routine will give you some structure to your day, and I think that that will help you a lot. 🙂
