Struggling with ADD: How Can I Write Again?

How to overcome ADD so I can write again. So I was diagnosed with ADD when I was younger. It didn't really bother me all too much but now that I am in my late twenties I have noticed a dramatic increase in symptoms. I have trouble sleeping, I forget how to spell words which make no sense because I am a writer, I am forgetting chores and simple tasks not even an hour later, and I can't bring myself to write even though I desperately want to. I see my psychiatric doctor on Tuesday and bring up these things but in the meantime, is there any way I can write again? Should I use outlines, drafts, or something else? Not writing hurts terribly since it is my passion and major coping skill so any help is greatly appreciated.
