Is there such a thing as a smiling disorder?

i smile a lot, as in a lot a lot. i cant stop smiling and even when im in tears im smiling or when im mad or yelling i smile. i always smile and people notice that. they ask me why i smile a lot and i dont know what to say. i looked up smiling disorders and what i found was an article entitled, "Specific Impairment of Smiling Increases the Severity of Depressive
Symptoms in Patients with Facial Neuromuscular Disorders" and i read some of it but stopped cause i dont really know whether people are born with facil neuromuscular disorders or if they develope it or what. i'm not up to researching more about it so i figured i'd ask here. is there such a thing as a smiling siorder where the person smiles uncontrolably?

I know lol, I smile alot as well and I don't even like too. Some say it's a nervous tick, but it could also be a mental disturbance. Im hoping not though. I also have a friend who smiles alot alot! Smiling is okay though.

I smile alot as well for no reason. I've heard of the same thing as it being a nervous tick. But I smile at even sad things. It's really weird :S Report It

If it is a disorder i have the same thing cuz i constantly smile and i cant help it
