  As I said, this is literally the only thing I can be 100% sure exists.

How can you be 100% confident something exists if you don't even know what it is? That's literally impossible, on a logical level. You can't hold a belief about a concept you don't have -- it would be like a pointer to memory that doesn't exist (i.e. useless, invalid, and erroneous).

Certainly you're aware of things. There are some relevant phenomenological concepts that you hold beliefs about, just like there were real symptoms being described by the Humours system. But you have no justification for bundling them all together into something called "consciousness", which coincidentally comes packed with other, completely unproven assertions.

"Certainly you're aware of things."

Seems you agree with me, then. The "you" i.e. me being aware is what I'm certain exists. I'm not sure what other assertions you think are bundled in there, seems like just the one thing to me.
