Just another diary of a mythical-to-be

Question

Btw this is not mythical related

So I'm pretty sure i have this thing called flat affect. It's basically when a person doesn't show facial expressions. No idea what could be causing mine but i have a question for people that can show facial expressions.

How?? Does it just happen naturally or do you move your face?? Is it sometimes one and sometimes the other one?? I want a answer to this pleaseee i won't be able to stop thinking about it until i get a answer

Edit: i wonder if that's why people don't come and talk to me. They never no what I'm thinking or feeling. Although thinking about it i can make facial expressions but just not naturally if that makes sense. Like i can fake it if that makes any sense. I act differently with different people for example when with J i act like my "self" as in the happy oblivious child me. Meanwhile with another friend (forgot what name i gave her) I'll act like a chaotic parent cause that's how she thinks of me as and if i were to change it to who i really am i don't even know who i would be I'm so used to changing my personality to who they think i am that i don't even rember who i am now I've been doing it for so long that i just start doing it i don't want them to leave me again i don't want to be alone again 

But hey that's a topic for another chapter. Also that went from 1 to a 100 real fast
