Yes. I experience specific symptoms directly from general anxiety: my senses are heightened, my stomach feels upset, I feel lightheaded and sometimes dizzy or off balance, tension headaches. The hardest part of it, though, is a tie between my energy being zapped and experiencing the upset stomach (pains and / or gerd).

I is especially difficult if I have experienced a full on panic / anxiety attack though. The F/F goes into overdrive. After, I am just simply exhausted. All the worry, stress, fear, acute awareness it all feeds into itself, and in the aftermath (after I have calmed down), I feel like I have been hit by a bus. I have no energy, my body hurts, I feel weak and all I want to do is drink fluids and sleep. It definitely takes its toll.
