Silliness aside, I've always believed that all artists are Manic Depressives( yes they who know these things call it something else these days). You have bouts of frenzied creation followed by "writers block"--a lack of inspiration. And this goes in cycles--up, down, up down. Or I could just be nuts! People have wondered. However, I've seen some real psychos . We all don't qualify, unless one morning you discover you seam ripper's got blood on it and your DH is missing.
