Nobody had to tell me. As a child, I worried constantly and had tics. Thankfully, the latter disappeared. As an adult I worry constantly and have tremors, which escalate along with the tremors. During what I would call my few "panic attacks" I showed up at the ER with my tongue stuck to the roof of my mouth in a hard spasm and feeling very . . .well . . .anxious. Hard to vocalize what your problem is in that condition!
