Am I the only one?

Am I the only one that finds it harder or even impossible sometimes to create when I am at low points in my mind or really feeling things or...

Basically it's harder to create, write, draw, the more I NEED an outlet or experience emotions to express I suppose. It seems like it's the opposite case for artists, but maybe they really have to push themselves. I don't know, don't get me wrong, I still do create in such states, often not, but I still do. Or rather it takes a lot to get myself there.

Edit: Even after I start or am in the middle of creating, not just getting started.
