What is the main idea of Dionne Brand's poem "Hard Against the Soul"? What message is she trying to convey?

From an interview with Brand.

I wanted to come back to “Hard Against the Soul,” because there was something I had begun to say that didn't work itself out. I usually write in blocks, and I needed to say the rest. I needed to fully come out as a lesbian; I needed to say what that did in terms of how I was going to speak now as a poet. Much of my work before didn't deal with sexuality as politics; somehow I've gotten a deeper, more honest sense of myself since coming out. The other thing is, I never write until it is time to write. I suppose I could have dashed off a few love poems here and there, but until the thing can be said properly, and I hope it is said properly, I don't think it should be said.
