Sometimes Ill be really sad or scared or anxious or completely shutting off emotion and I find myself smiling unknowingly as if Im just having the time of my life. I look like a kid in dosney world... Flexing all the smile muscles into a perfectly believable smile exactly the same as when Im smiling for real... Its like my face sometimes disconnects from how I actually feel. I dont know if thats a bpd thing or if Im a weirdo or what.
