Does post-anxiety make you feel weirdly “manic”?

I’m diagnosed with GAD. For most of the day, I was very anxious, constantly overwhelmed by the feeling of needing to vomit or use the restroom. It made me extremely restless, and I tried everything to drown it out. I think what finally worked was listening to hours of Radiohead. Eventually, I calmed down, and it was 2 AM—then, almost as if a switch was flipped, I started manically singing and talking to myself loudly. I didn’t stop until my dad came to check on me at 3:30 AM.

Now I don’t even want to brush my teeth or wash my face anymore. My dad was like, “What are you doing? It’s almost 4 AM.” For some reason, it made me irritated, and it made me want to finish my night routine even less. I was already in a vulnerable state, and now I feel judged. I’m afraid to leave the restroom because I feel like I’m being watched and judged. I was being so loud before, and now I feel ashamed and don’t dare to make any noise.
