I can't yawn!
Most of the time I wanna yawn, I can't do it. I'm like with my mouth all opened, streatching all my body, moving me, but I cant finish it! I can do it the 10% of time, it's very frustrating. And now at this very moment i'm thinking of it and i'm triyin' to yawn again. Socially it's a problem because people at work or in my personal life think I've no respect maybe.. Docs can't do nothing about it: they say I've to be less nervious.
