Just to note: I do not mean after the anxiety, or after anxiety or panic attack.

When faced with an anxious situation or thinking anxious thoughts, I usually go the opposite way of typical anxiety symptoms.

I get like these waves of tiredness and fatigue that make me feel sort of sleepy, as if my body is telling me to lie down and go to sleep?

This is hard to deal with when outside, because I feel like I need to take a nap and it's really overwhelming.

Does this happen to anyone else?
