One word I'd use to describe my anxiety is.....

all consuming

Painful

Skeptical.

("Are you SURE the breathing difficulties, dry mouth, throat discomfort, and new pins-and-needles sensations are just coming from me? You could be dying--") (NO ONE ASKED YOU PATRICE)

Hell.

My anxiety is the beast in mind.

Repetitive

Despair

Constant

Never ending

inconvenient
