I itch, but only metaphorically. It's not a physical sensation, merely a tick, like clock hands make but more deafening. I feel it in my skin, like bugs crawling, creating passage ways to safe places that I didn't know existed, and I've still yet to actually find them
It just isn't easy to explain anxiety to someone whose never had it. It's like trying to teach a penguin to fly with an anvil strapped to its chest. Originally it was impossible, but when you have anxiety, you find ways to make it even more so.
