Epistemological skepticism sure is a belief. A strong belief on your side?

I am profoundly sure, I am certain I exist and that a reality outside myself exists. Worse, I strongly believe knowing this external reality is possible, desirable and accurate.

How suspicious does that make me?

It means you haven't read Hume, or, in general, taken philosophy seriously. An academic philosopher might still come to the same conclusions as you (there is an academic philosopher for every possible position), but they'd never claim the certainty you do.
