Life on the spectrum is a literal roller coaster that whirls from giddy nervousness to completely overwhelming anxiety, a gnawing, jittery, ever-present sensation of waiting for the threat . . . waiting for the fear.

We spectrumites, whose bodies and minds are wired a little differently, live with varying levels and intensities of almost perpetual anxiety.
