i eat faster than everyone around me because school lunch cafeteria habit/PTSD/anxiety. i have sensory issues with the sound or sight of other people eating (sounds of chewing/talking with full mouth and sights of chewed food absolutely immediately disgust me on a subconscious instinctual level, its like if someone screamed into my ear suddenly or hit me on the head really hard) so i always had to get it over with ASAP so i could go be somewhere alone.
