Everything I could never say

I wonder if its normal to feel this. My throat closes up so I don't speak, and if I try it feels like I can't breathe. The harder I try it feels like something is stuck in my throat, trying to crawl its way out of my mouth. My eyes dart around, desperately looking for somewhere to escape. If I don't get out of there it gets worse. My skin crawls with a cold chill around the frame of my face but at the same time the center of my face feels like it's searing hot.
