After a big period of anxiety is resolved (I just got negative medical test results) I often end up in this state I call an anxiety hangover. I feel drained, tired and low. I also feel like sounds are too loud. I'm at work and people are just chatting in the staff room, but it feels like nails on a chalkboard. I'm craving silence and alone time. 

This happens to me every time I pass through a period of intense anxiety, usually lasts for a few days. Anyone else?
